When it comes to Jinn I'll be using the things I used from Meetra vs Qui-Gon, as there is nothing more I can add.
Dueling Abilities
Qui-Gon Jinn
Jedi Master Qui-Gon Jinn was recognised as one of the best swordsman in the entire history of the Jedi Order.
Jinn was generally regarded as one of the best pure swordsmen the Order had ever seen.
-Source: The Complete Star Wars Encyclopedia
A Jedi Master who was known as one of the Order's most formidable members, but his recklessness and his devotion to bizarre causes kept him from becoming a member of the Jedi Council.
-Source: The Complete Star Wars Encyclopedia
It was stated that Qui-Gon Jinn is a better duelist than Anoon Bandara and was compared to Mace Windu.
Renowned for his skill with the lightsaber, Jedi Master Anoon Bondara is regarded by many of his peers and all of his apprentices as a role model whose combat prowess is unmatched in the Jedi Order. Bondara would disagree with this assesment. During his tenure at the Jedi Temple on Coruscant, he spars with superior lightsaber duelists such as Qui-Gon Jinn and Mace Windu. Although he humbles himself when compared to their skill, Bondara's prowess is nontheless considerable.
-Source: Jedi Academy: Training Manual
Being better than Bondara is significant, because Bondara has provided a decent fight to Darth Maul.
By the time of The Phantom Menace, Qui-Gon Jinn was still superior to his Padawan Obi-Wan Kenobi.
They had fought together before, and they knew each other's moves. Qui-Gon had trained Obi-Wan, and while the younger Jedi was not yet his equal, he believed that one day Obi-Wan would be better than he had ever been.
-Source: The Phantom Menace
It was also stated that Jinn has mastered many fighting techniques.
Qui-Gon Jinn's lightsaber may not be as ornate as that of his mentor, Count Dooku, but true to his rebellious ways, he used it to master the same classical fighting techniques as well as untraditional combat forms from across the galaxy.

Qui-Gon contends with Darth Maul twice, almost killing him on Tatooine
https://www.youtube.com/watch?v=yHqdESArkqU
https://www.youtube.com/watch?v=DMylmOlot4g
The Jedi activated his own greenbladed lightsaber and raised it fast to block Maul's sweeping blade. The lightsabers met with a bright flash of energy before Maul landed on his feet in a tight crouch. The pain in his leg was exquisite. Up close, Maul saw the Jedi was a big man. The Jedi shouted at the boy to go. Maul swung hard with his lightsaber but the Jedi blocked the blow. The Jedi shouted, "Tell them to take off!" As the boy ran for the Queen's ship. Maul lashed out at the Jedi again and again, but the Jedi blocked each blow. Maul was suddenly aware that the Jedi seemed to anticipate each lunge and jab, as if he knew how Maul would move before Maul himself knew. Maul drew from the dark side of the Force and began to move faster, increasing the speed of his lunges along with his footwork. The Jedi kept up with Maul, but Maul soon sensed... He's getting tired. Maul felt the pain in his leg become more intense. He became angry at himself for being wounded, used the anger to fuel the dark side, and directed his rage at the Jedi. Maul was certain he would defeat his opponent. He will fall heavily, like a monument. But the Jedi did not falter. As Maul spun and moved around the Jedi, he saw the Queen's starship lift off. He also saw the hoarding ramp was still extended. Maul leaped over the Jed, blocking his path to the rising ship, as their lightsabers continued to weave and smash into each other. The ship had just moved above their position when the Jedi leaped straight up and landed on the extended ramp, his lightsaber still blazing
-Source: Star Wars: The Wrath of Darth Maul
The Jedi meets my first blow, blocking it. He has expected my flying maneuver.
If an opponent can read you, the fight is over. I don't like that the Jedi was perfectly prepared for my first blow. Within seconds, I throw away my usual combinations and strategies. This Jedi seems to know how I will move before I do.
But he cannot match my strength. I sense this. And I feel his surprise at this. Yet he does not let his puzzlement slow him down. I tell myself that this man has never met an enemy like me before, and it frightens him.
Your fear is justified. Prepare to die.
I accelerate my pace, calling on my anger to increase my power. My footwork has never been so brilliant. I use the shifting sand as resistance. My lightness and quickness will defeat this man, with his large body, his heavy movements.
But he is graceful, this Jedi. The sand doesn't see to hamper him. He is never off balance, no matter where or how I strike.
Our blows send shudders through my body. He meets my strength. Our lightsabers clash and sizzle. Dust and sand rise around us. I never lose my rhythm.
The Jedi calls to the boy, tells him to go back to the ship. The cowardly boy runs off. After I defeat my enemy, I will find the second Jedi.
But I must confess that this Jedi is a challenge. If I leap, he is with me. If I turn, he follows me. He meets my ferocity with his own. His lightsaber swirls and hums, and several times comes closer than I like.
It is because of my wound. It has slowed me down somewhat. It is almost imperceptible, but it is there. The Jedi has an advantage. I am not at my best.
This realization sends more rage pumping into my body. I am angry at myself, but I use the anger to fuel the dark side. I feel the Force come from the Jedi and I send it back to him, showing him that I, too, have a connection, and it is stronger than his. I launch a furious counterattack. I feel like the Jedi is beginning to tire, and triumph rises like a red mist before my eyes. I gain the advantage. I am winning. I will defeat him.
I have been surprised at his skill, but now I am confident of victory. I will savor each moment of this battle.
Even through his fatigue, his blows still have power. He is a large man with impressive strength. He will fall heavily, like a monument.
I feel a savage pleasure course through me. His weakness feeds my power. I drive him back, spin around when he parries, drive him back again. The dust chokes my throat, but I don't notice.
-Source:Episode I Journal: Darth Maul
While it should be noted that Maul had a leg injury, I don't see this of being much relevance. Why? Jinn was a better duelist than Bondara, someone who gave Maul a decent fight.
The Twi'lek Jedi's leap, guided by the Force, landed him squarely behind Maul on the rear engine housing of the T- shaped bike. The action took Maul by surprise; he had not expected such a courageous, if foolhardy, deed.
Unexpected as the move was, however, Maul was still able to block the slash of the other's lightsaber with his own energy blade. He quickly activated the speeder's autopilot, then twisted around in the saddle, thrusting his weapon at the Jedi's chest. The Jedi blocked the blow and countered with another.
Maul knew the battle could not continue this way. The speeder bike's autopilot was not sophisticated enough to chart a safe course at high speed through the torturous windings of the surface streets. He grabbed the handlebar and jerked the speeder toward a docking platform on a nearby building, about thirty meters above the street. They shot by the skycar, which had slowed after the Jedi left it, and rose toward the shelf. As the ledge came within range of the autopilot's seniors, the speeder slowed, then settled down to a landing on the extruded slab of ferrocrete.
The Sith and the Jedi leapt from the speeder bike onto the platform to continue their battle. The dock-Ing ledge was only about ten meters by fifteen, barely enough room to maneuver in. Maul knew he had to dispatch the Jedi quickly, before Pavan once again vanished into the labyrinth of Coruscant's downlevels. He pressed the attack viciously, blocking and thrusting, the twin radiant blades spinning a web of light about him.
The Jedi was obviously a master of the teras kasi fighting arts, as well, judging by the smooth way he parried and counterattacked. Still, within the first few moments of the engagement, Darth Maul knew that he himself was the superior fighter. He could tell that the Jedi knew it, too, but Maul also knew that it didn't matter. The Jedi was committed to stopping the Sith, or at the very least slowing him down enough to let the others get away, even if it meant giving his own life to do so.
Maul bared his teeth. He would not lose his quarry again! He doubled his efforts, pressing the attack hard, hammering away at the Twi'lek's defenses. The Jedi gave ground, but Maul was still unable to slash through his guard.
-Source: Darth Maul Shadow Hunter
Definitely not in the same class as her Master, the Twi'lek who had destroyed his speeder bike. He had been a worthy adversary. Not as good as Maul, of course, but that was to be expected.
-Source: Darth Maul Shadow Hunter
Not only this but by the time of Naboo Maul's injury had healed and Jinn still contended with Maul for a decent amount of time, even when Maul had taken Qui-Gon to a location of his choice. It should also be noted that Maul only started winning on Tatooine because Jinn was getting tired, not because Maul was a better duelist.
Qui-Gon Jinn was a master of form 4 Ataru, however staying true to his rebel ways, he retooled it, going against the textbook nature.
Instead of relying on acrobatics which is usually typical of Ataru users, Jinn chose to rely on his strength more than anything, which allowed him to remain in fights longer than most Ataru users.
As a master of Ataru, Jinn often used physical strikes with his lightsaber technique, as seen here.
Qui-Gon was also a very adaptable fighter, able to fight a long time against Maul's saberstaff.
He was able to perfectly adapt to Xanatos whipping out a second lightsaber out of nowhere.
A second lightsaber was suddenly in his hand. Startled, Qui-Gon lost his focus for an instant. There was only one person to whom that lightsaber could belong. "And where is your new apprentice?" Xanatos sneered. So Xanatos had been responsible for Obi-Wan's disappearance. Now he knew it for sure. Xanatos faked a charge to the left, went right, then danced back to the left again. Qui-Gon remembered the move from the Temple. He easily blocked the blow.
-Source: Star Wars Jedi Apprentice: The Dark Rival
Ex Jedi Aurra Sing also whipped out a second blade from no where, yet soon after she claimed Jinn and Obi-Wan were more than she bargained for.
Wrecks Xanatos twice, also showing impressive physical strength.
In the end, Qui-Gon was a top tier council level duelist who is very underestimated by many.
Kyle Katarn
Kyle Katarn was a great duelist and was stated to have been one of the best of his time.
"What about these impulses?" Kyle Katarn asked. With brown hair, brown eyes, and a tan shirt tucked into brown breeches, he looked like a farmer about to return to his fields instead of one of the Jedi order's most famous and skilled members. "Are you talking about Force impulses?"
-Source: Dark Nest I: The Joiner King
Extremely powerful Sith Lord Darth Caedus considered Kyle Katarn a threat.
Three Jedi Knights: the younger Horn, the Falleen Mithric, the Bothan Hu'lya. He resisted the urge to snort. Separately or collectively, these Jedi Knights were no match for him.
Katarn, though, was a threat.
-Source: Legacy of the Force Fury
Kyle Katarn was a battlemaster of the Jedi Order, meaning he'd have mastery of all known lightsaber forms (excluding Vaapad).
During his fight with Maw, Kyle seems to beat him through outsmarting him.
"I am Maw... prepare to die!"
"Maybe," Kyle replied calmly, "remembering that my friend Rahn already cut you down to size."
The effect was electrifying. Maw's face turned purple with anger, and he uttered a roar of pure, undiluted rage. He accelerated with far greater speed than Kyle had anticipated.
The Rebel fell backward, allowed the Dark Jedi to pass over him, and slashed upward. Maw bellowed with pain, lost his concentration, and hit the deck. The lightsaber sailed out of his hand, and debris rained onto his head and shoulders.
Kyle took a single step forward, eyed his opponent's back, but couldn't bring himself to do it. Maw supported himself with his fists, turned, and looked upward.
-Source: Dark Forces: Jedi Knight
Kyle defeated many notable Dark Jedi at this time, which is made more impressive when you consider Kyle had barely any training.
Unlike most Jedi, who serve an apprenticeship under a Master, Kyle had been forced to work on his talents on his own, or almost on his own, since he did receive occasional guidance from the now-disembodied Jedi known as Rahn.
-Source: Dark Forces: Jedi Knight
Most impressively, Katarn holds his own against incredibly skilled and powerful Dark Lord Darth Caedus
Katarn ignited his lightsaber as he came to a stop a few meters away. "Care to surrender, Colonel Solo?"
"Not to a traitor." Caedus looked at the other three as their Force-augmented sprints came to an end, leaving them in a semicircle before him. Three Jedi Knights: the younger Horn, the Falleen Mithric, the Bothan Hu'lya. He resisted the urge to snort. Separately or collectively, these Jedi Knights were no match for him.
Katarn, though, was a threat. Still, the Jedi had only moments before GA reinforcements would arrive. Their attack was already a failure.
He sensed Katarn's attack, threw up his blade in a block so well practiced that his muscle memory could have performed it while he slept. With his free hand, he gestured at the Bothan Jedi. She was suddenly airborne, hurtling sideways to slam into the Falleen, knocking them both down.
Katarn's blade struck his, rebounded with a snap-hiss. and came around from the other side as the Jedi Master executed a lightning-fast spin. Caedus stepped back from it. not engaging the blade. He watched the blade flash harmlessly past him.
He stepped forward again into a side kick, aimed not at Katarn but at the onrushing Valin Horn. His boot heel caught the Jedi Knight on the point of his chin, knocking Horn backward off his feet. Two seconds had passed since the attack began.
...
Only Seha's head protruded from the pavement hatch as she watched her four companions assault Colonel Solo.
In one sense, it was a beautiful and brilliant thing to see. The five combatants moved as though they'd been choreographing this event for years and had planned, all along, that the two sides would somehow be even. Each time the lightsabers came together, the resulting flash of light, slightly greater than two glows by themselves, cast the five combatants into relief. Around them, blinded GAG troopers withdrew, finding one another by touch, keeping their blasters up and at the ready, waiting for the moment when their sight would return and allow them to open fire. Above, though at a distance from the Senate Building, the trails of airspeeder lights glimmered in their passage.
And Seha still had one task to perform.
In her free hand she held a patch of black cloth. It was square, five centimeters to a side, and very soft and pliant, despite the fact that its center layer consisted of circuitry embedded in a flexible polymer.
One side was covered by a transparent layer of flimsi. With her teeth, she worried an edge of the flimsi free, then pulled the whole layer off, dropping it into the access hole she occupied. The removal of the flimsi exposed a layer of adhesive.
With her own Force powers, so much less subtle than those of her allies, she sent the cloth patch flying, centimeters above ground level, toward the fight.
But she couldn't send it on to her target, not yet. Master Katarn had been clear about that. She had to wait until things were at their most chaotic, their most distracting.
So she guided the patch ever closer to the fight, but waited, waited...
...
Ten seconds.
Caedus rolled out of Katarn's kick to his head, catching a scrape along his cheek, and swung at the Master's leg, but Kolir's blade intercepted his before it bit into flesh. His strength batted her weapon away, but she had deflected his blow and spared Katarn an amputation.
They're coordinating. Good for them. Bad for me.
Caedus heard a siren-an oncoming GAG vehicle. No, two-maybe three.
He allowed himself a certain satisfaction at their speed of response. He hadn't expected anything of the sort for another half minute.
Then, from the corner of his eye, he saw the first oncoming vehicle, an aging Sentinel-class armored shuttle. It was yellow, with spots of rust. He could not make out its markings without looking at it, but he knew it was not in GAG or Alliance colors. Entering airspace above the plaza, it began a dangerously steep and fast repulsorlift descent. Behind it came three GAG airspeeders, one of them firing a top-mounted laser at the shuttle.
Ah. So they were not responding with brilliant speed to an alarm. They were chasing the Jedi escape vehicle. Caedus swung at Horn, a blow meant not to connect but to cause the young Jedi to flinch away into the path of the Falleen, which he did. While they were interfering with each other, Caedus gestured at the Bothan Jedi, hurling her toward Katarn.
Katarn hurled his lightsaber off to the side and caught Hu'lya with both hands, preventing her from falling, prepared to pull her out of harm's way if Caedus followed through.
Caedus did not. He kept his senses on Katarn's light-saber, and, when it vectored to fly toward him from the side, he negligently swatted it away with his own blade.
Fifteen seconds.
Caedus gave Katarn and Hu'lya a little smile. "You could save yourselves a lot of pain by telling me now where Luke has set up the new Jedi headquarters. I swear, when you are in my hands, you will answer that question."
The Bothan got her feet back under her and stood at the ready.
Katarn caught his returning lightsaber. "Meaning you will torture us to death. Are you listening to yourself, Jacen? Do you even know who you are anymore?"
"I do. It's you who have no idea who I am."
He felt Force energy growing within Mithric and Horn. He gestured, telekinetically yanking the Bothan forward, positioning her between him and them. He felt their Force exertion as it was suddenly cut off.
Katarn advanced, lightsaber at the ready. Caedus withdrew before him. With part of his awareness, he was keeping track of the four inbound vehicles, plotting their trajectories. . .
One of the GAG vehicles was circling ahead and to starboard of the descending shuttle. Its arc, intended to put it toward the bow of the shuttle so it could fire on the cockpit, would bring it near the combatants, just a few meters above them. The pilot's maneuver was smooth, the vehicle clearly under control. Caedus could see the Jedi barely registering its presence, since it did not figure into the combat.
Caedus reached out a hand as if intending to hurl Katarn away from him. The Master raised his own hand, a deflecting gesture. But Caedus exerted himself against the oncom-ing GAG speeder, yanking it down and toward all of them.
A moment's inattention or focus elsewhere. That's all it ever took. By the time Katarn felt the speeder coming toward him-spinning, its stern a mere two meters from his back-it was already too late for him to send a command even to Force-augmented nerves and muscles. His face changed with the awareness of danger.
Then the speeder's port quarter hit his back, hurling him forward to slam into Caedus. The speeder, continuing its out-of-control motion, slid through the location of the other Jedi, knocking Hu'lya to the permacrete, causing Horn and Mithric to leap to safety.
Katarn now stood so close to Caedus that every facial feature was visible, every scar and line in his weathered face, every hair on his brow, mustache, and beard.
Caedus felt a rush of satisfaction, enjoyment, as Katarn's expression turned from one of surprise to pain. Katarn looked down to see Caedus's lightsaber buried to its hilt in his chest.
A noise, something halfway between a groan and a death rattle, emerged from Katarn's lips. Smiling, Caedus yanked his lightsaber free and let the stricken Jedi Master fall face-first on the pavement.

Summary
While both are great duelists, I think Qui-Gon gets an edge. His application of Ataru would ensure he stays in the fight long and his adaptability means he'd have no trouble reading Katarn's movements. In terms of pure skill, he also surpasses Katarn, being regarded as a prodigy and one of the most skilled swordsman of the
history of the Jedi Order.
Dueling Abilities = Qui-Gon Jinn
Force Abilities
Qui-Gon Jinn
Jinn was an incredibly powerful Jedi.
Along with Plo Koon and Tholme, Jinn collapses a cave.
He easily hurls Feemor while in a sparring session
He pulls Quinlan Vos and Obi-Wan Kenobi from a river with casual ease. This is impressive, because the river had enough force to pull the two Jedi down.
He's even mind tricked a hutt, a species known to be resistant to mind tricks.
It was time to pay a visit to Offworld Headquarters. Offworld did not try to beautify their Bandomeer office. The building, a black, windowless block, echoed the grim mines that surrounded it. Qui-Gon entered the center hall with its azurite-studded walls. The mineral was its only decoration. A Hutt security guard sat behind a black cube that served as a desk. His body rolled past the confines of the desk. He turned flat, dead eyes toward Qui-Gon.
"I have come to see Xanatos," Qui-Gon said.
"Move, wretch," the Hutt replied, bored. "Take your petty complaints to you immediate supervisor. There's no one here anyway. Xanatos is on an exploration trip to the northern mine quadrant."
The Hutt reached for a blaster. So much for corporate hospitality. Qui-Gon didn't move a muscle. He concentrated on the Hutt's greasy mind, pulling in energy from the Force.
"Perhaps I should wait in his private office," he said.
"You should wait in his private office." The Hutt repeated tonelessly.
"Take the restricted tube to Horizontal Thirty."
"Security controls should be lifted," Qui-Gon said.
"All security controls shall be lifted.''
-Source: Jedi Apprentice: The Dark Rival
His mastery and attunement to the force was so great, when he died he became a force spirit, something Yoda couldn't do until Qui-Gon taught him!
Yoda heard the voice of Qui-Gon Jinn from beyond the grave and the fallen Jedi led him on a journey of discovery. It was through this revelation that Yoda unlocked the secret of Force immortality.
-Source: Star Wars Annual 2016
Even Mace acknowledged Jinn's relation with the force.
The Force did not disagree. Qui-Gon had had a special relationship with the Force, and he had taught his apprentice well.
-Source : Rogue Planet
The fact that Jinn does everything he does with such casual ease showcases an extreme amount of mastery and leaves no doubt in my mind that if he used the force more offensively he could easily b Obi-Wan level.
Since his mastery is so great, it's unlikely his force wall would be broken with ease as well.
Kyle Katarn
Kyle Katarn was perhaps best known for his force abilities, using both light side abilities and dark side abilities. He believed that no power was inherently good or bad, it's how you use them that matters.
He had an ability called darkshear, which is a dark side power that attacks the mind of an opponent, it can also cause physical pain.
The Jedi accessed the knowledge gained from the long-dead Tal, blocked the mental strike and answered with an attack of his own. He launched a head cut from the third position, flexed his wrist, and extended his arm. Though a good deal lighter than its metal counterpart, the Jedi energy weapon possessed similar characteristics. It could penetrate like a rapier and cut like a saber. A double-edged saber.
Sariss blocked the mental blow, wondered where Katarn had garnered such knowledge, and found herself under attack.
-Source: Dark Forces: Jedi Knight
Kyle took advantage of the opportunity by summoning the Force, forging a spear of midnight black, and hurling it toward his opponent's chest.
-Source: Dark Forces: Jedi Knight
It should be noted that these are the only two situations when Katarn has used this ability(to my knowledge), and the time it worked was when his opponent was distracted.
Kyle was powerful with his use of telekinesis, able to build a wall of rubble along others to shield Luke, Mara and Jacen.
Kyle Katarn arrived in the same instant, emerging from the flotsam with half a dozen other Jedi. They quickly drove the last of the Gorog warriors away, lacing the darkness with blaster bolts and flinging thermal detonators around like confetti, using the Force to create a protective shell of rubble around the Skywalkers and Jacen.
-Source: Dark Nest III: Swarm War
Kyle has been shown easily hurling Yuuzahn Vong and numerous people at once.
Kyle has lifted numerous amounts of rubble, though with great strain, however he was on a dark side nexus when this happened and would have been hindered because of it.
Summary
Between the two I see no major power gap, though I do believe that Jinn has a superior mastery and attunement to the force, which makes him penetrating Kyle's defenses more likely Kyle penetrating Jinn's. That being said, Jinn hasn't really been depicted using an extreme amount of force powers in a serious lightsaber duel, whereas Katarn has. Though the usefulness of these powers are likely to be minimal, some offensive use with them are better than none.
Force Abilities = Kyle Katarn
Physical Abilities
Qui-Gon Jinn
Qui-Gon Jinn was incredibly strong, able to meet the strength of Darth Maul, the guy who could rip through a Wampa's torso. Wampas are creatures known to have tanked blaster fire and missiles.
I accelerate my pace, calling on my anger to increase my power. My footwork has never been so brilliant. Iuse the shifting sand as resistance. My lightness and quickness will defeat this man, with his large body, his heavy movements. But he is graceful, this Jedi. The sand doesn't seem to hamper him. He is never off balance, no matter where or how I strike. Our blows send shudders through my body. He meets my strength. Our lightsabers clash and sizzle. Dust and sand rise around us. I never lose my rhythm.
-Source: Episode I Journal: Darth Maul
Summoning whatever remained of his strength, Maul fired himself at the beast. Hooking his hands into claws, he plunged them through its fur, ripping into the soft tissue of its torso... ...Shoving his hands deeper, he sank both arms in up to the elbow, beneath its rib cage and into its thoracic cavity, groping until he found what he was looking for— the slick, pulsating mass of its heart. Maul grabbed it, laced his fingers together, and squeezed. The wampa’s heart burst between his fingers like a dense and fibrous flower."
- Source: Maul: Lockdown
He was also able to send Maul hurling and as seen above in the dueling abilities section he wrecks Xanatos with his physical strength.
Jinn was also a tank, able to take a lot of punishment and keep on going.
He survives this injury
The blade bit deep into Qui-Gon's right shoulder, driving him to the floor.

The Pirate chieftan's vibro-ax had slashed Qui-Gon across the back of his shoulders, down to the ribs.
-Source: Star Wars Jedi Apprentice: The Rising Force
He tanks a grenade like attack and does acrobatics seconds after.
The impact knocked turned the boulder into a bomb, shattering it into large pieces of shrapnel that seemed to fly at Qui-Gon in slow motion. Qui-Gon was hit in the chest. Badly. The impact knocked him backward, his lightsaber leaving his grip and flying meters away from him.
-Source: Jedi Apprentice: The Mark of the Crown
Qui-Gon pushed himself to his feet. The pain hit him, red and searing, and he'd been hit by a chunk of boulder in the leg as well. He called on the force to help his body respond, his mind to clear. The speeder was bearing down on him again. He leaped to avoid cannon fire and sommersaulted over the low flying speeder, striking down as he did so at the control panel.
-Source: Jedi Apprentice: The Mark of the Crown
He continues fighting after this
He hit Xanatos in midair. Their bodies connected like mountains of hard rock. There was no give to Xanatos' muscles, no yielding in Qui-Gon. The clash was titanic. Qui-Gon felt the shock of it move through his bones. For a moment, Xanatos gripped Qui-Gon's arm, forcing them to remain entangled.
-Source: Jedi Apprentice: The Deadly Hunter
Jinn also had impressive stamina, able to fight for an incredible amount of time. Even when exhausted, he did not stop or make a mistake.
The match was not timed. It would only end when one of them scored a blow. Exhaustion began to slow their moves, but they did not stop or make mistakes. He could hear the murmur among the spectators, wondering how long the two students could continue. He sensed more Jedi Masters arriving.
Tahl's face was a mask. She had gone deep within herself, past her exhaustion to a place of sheer will. Qui-Gon had never felt so tired. His arm muscles shook. His legs felt watery. They trembled. Still he did not stop or make a mistake.

Kyle Katarn
Kyle himself was also a tank, even more so than Qui-Gon.
He tanks a force blast that disintegrated a ramp and moved a ship
The Dark Jedi drew upon the energy that leaked out of the Valley, gave it shape, and hurled the construct at Kyle's chest. The blast threw the Rebel backward onto the loading ramp. He staggered and had just managed to reestablish his footing when a second, more powerful explosion hurled him back into the cargo ship. The lock sensed his presence, and the hatch started to close. The ramp disintegrated.
The ship tilted away, and fell toward the rocks below.
-Source: Dark Forces: Jedi Knight
He tanks a speeder being slammed into him
Caedus reached out a hand as if intending to hurl Katarn away from him. The Master raised his own hand, a deflecting gesture. But Caedus exerted himself against the oncom-ing GAG speeder, yanking it down and toward all of them.
A moment's inattention or focus elsewhere. That's all it ever took. By the time Katarn felt the speeder coming toward him-spinning, its stern a mere two meters from his back-it was already too late for him to send a command even to Force-augmented nerves and muscles. His face changed with the awareness of danger.
Then the speeder's port quarter hit his back, hurling him forward to slam into Caedus.

Most impressively, Kyle survived a lightsaber being buried in his chest, something Qui-Gon couldn't do
Caedus felt a rush of satisfaction, enjoyment, as Katarn's expression turned from one of surprise to pain. Katarn looked down to see Caedus's lightsaber buried to its hilt in his chest.
A noise, something halfway between a groan and a death rattle, emerged from Katarn's lips. Smiling, Caedus yanked his lightsaber free and let the stricken Jedi Master fall face-first on the pavement.
-Source: Legacy of the Force: Fury
Summary
Kyle has Qui-Gon beat in terms of durability, but I see that at his only edge here. Qui-Gon likely has better stamina, much better strength and likely better speed.
Physical Abilities = Qui-Gon Jinn
Conclusion
Their skill with the blade is pretty close, but Qui-Gon gets the edge. Their use of the force was near equal, but Kyle would get the edge. In terms of their physical abilities, Qui-Gon gets an edge, Kyle only beating him in terms of durability. As Jinn did with Maul on Tatooine, Jinn would perfectly read Kyle's movements. Maul noted that if an opponent can read you, it's over, however like Maul, Kyle would change his tactics. Unlike the duel on Tatooine though, Jinn hadn't just been running in the desert and he's not going to tire easily. Also, Kyle doesn't have that rage boost that Maul had. Jinn would adapt to Katarn's style again and eventually cut him down. As mentioned in the force abilities section, I doubt Katarn's use of the force would be a deciding factor when against Jinn.
Winner = Qui-Gon Jinn
