We have seen them both in action and know they are both AWESOME swordsmen, but when pitched against each other who would win?!
Yoda. Yoda would be winning then Mace would have to crossover to the dark side to stay in the fight. But Mace is not as strong in the dark side as Sidious. Yoda would prevail.
using statistics Mace beat Palps Yoda didn't Mace apparently can defeat Dookuin a duel Yoda failed to "as wise as Master Yoda, as powerful as Master Windu" Anakin "...you'd rival master Yoda as swordsman (i thought i already did/) only in your mind my very young apprentice" Obi-Wan using these two quotes above shows what the writer wants you to think AOTC: Lucas wants you to believe Yoda is the best in ROTS he wants you to believe Windu is the best all in all, it depends on plot, and the pen of the writer who'd win. on in story point, it would depend on: situation enviroment use of the force and commitment/level headedness (for what it's worth, as I mention a lot, I study western/Eastern martial arts and swordplay, so these are my favourite threads, unfortunately though it might be locked )
Palps allowed himself to appear defenseless just in time for Anakin to walk in. He was not defeated. Mace was being toyed with. Yoda is more powerful.
thank you for not locking DB Darth Vader: I believe in EU it says that Mace once beat Dooku in duel training
This would be the longest duel in SW history if it happened, but I seriously don't know who would win, I'm thinking Mace because of his strength, but then again, Yoda is better at using the force.
Mace would win, obviously. He's a bad@ss with a lightsaber. That's like asking who would win if Ironman and Thor fought... While Thor theoretically has the power of a god, Ironman is still a bad@ss.
I realised I never answered the question: in light with what I said, I'd say it would be a close call, but I'd have to say Yoda, but only just
