Darth_Nefarus,
I agree with Arsenal's comment about you writing some Star Wars comics. Perhaps you've heard of the Infinites comics, they have to do with alternation versions of the Original Trilogy, none have been made for the Prequel Trilogy yet; but I am sure that after the release of Return Of The Sith they will be in the works. You should consider contacting LucasBooks and perhaps seeing if you could write an Infinities Comic Trilogy for Attacks Of The Clones.
As for the topic at hand, I vote Mace Windu. Mace is considered Yoda's equal, his form of Lightsaber combat (known as Vapaad or Vaapad if I remember correctly) is the closest to the Dark Side that is used by the Jedi Knights. Mace's style is just as aggressive as Dooku's, I believe he could take Dooku easily.
Mace: "Yo Count, yo boot's untied mother*censor*"
[Dooku looks down to his boot]
[Mace hacks off Dooku's head]
Mace: "You stupid *censor*, you fell for the dumbest *censor* trick in the god *censor* book of Jedi tricks!"
Sorry...
