Kyle Katarn vs Darth Sion.

While training students for Luke's Academy, Kyle senses a dark presence. He goes check, and finds Sion Force Choking a padawan, so they both start fighting.

Force.
Sabers.
All Out.

If Sion can die only once, then Kyle all rounds, every time.

Kyle. He's more than skilled and warrior-therapeutic enough to convince Sion to give up. He wins every round, regardless of the criteria for his success.

If Kyle doesn't get stabbed in the back thinking Sion is dead, he can win, but it's gonna require a hell lot of stamina. Fortunately for Kyle, his accomplishments in JK2 show that.

Proof Katarn can beat Jedi left and right and have a difficult duel with Atton Rand?

Kyle slaughters all rounds.

Someone show me any proof that Kyle has ever fought elite duelists like Atton Rand
