Mace is generally seen as one of the best (maybe the best) duelist that the Jedi Order has produced. Kirak was one of Vader's earliest victims but only lost his duel to Vader because he tried to trade his life in exchange for Vader promising not to drown a nearby town...of course Vader killed him and proceeded to drown the city.
Kirak was able to outduel Vader, understand his fighting style, the intention behind his attacks, and break Vader's force grip on him. He was someone who isolated himself from the Jedi and dedicated himself to fighting.
Who wins if these two revered duelists clashed?
