Luke Skywalker (Dark Empire) vs Mace Windu

Luke Skywalker as of Dark Empire II
Mace Windu as of Revenge of the Sith

R1: Sabers
R2: Force
R3: All out

Either way, but leaning Luke.

Luke fought a far more powerful Sidious than Windu caved against. Even if he lost without aid. Better yet, Windu can't perform on that level without the wealth of circumstances that clocked his Vaapad to 11.

Definitely Luke.

DE Luke is kind of unquantifiable to me, so I'll go with Windu.

Luke considering how impressive his duel was with DE Sidious (despite losing)

Luke makes him an hero.

Luke all rounds.

Luke.
