Revan is faster smarter and more effiecient. But for superbadness'd Vader would win you just feel the evil coming from vader (esp cloud city.) I am going with the fanatic that this would be a draw! But if I were a betting man (and an idiot) and have to say what are the factors! That suit vaders in can take a lot of punishment except from electrical attacks and so would win the long run. Revan would win if he went for the quick win! Revans just as go a force adapt as Revan because all the other jedi trained at that time (esp Malak) admired him for sheer power and presence in the force like Vader when he was a whinny boy!
I don't hate Vader but even with Bane "New Sith" (which sucks) if vader had found a weakness with sidious then he would have tried to get or become scrap! That is the way of the darkside! If someone says one more thing about sith magic which is only power which is from an artific and the users own power channeled from some source to produce darksde powers over a large area then I am going to use my own saber I lovingly made out of toothpicks to strike the next idiot down!
Vader is cool, he's bad and he's put more jedi to the force then can counted but that's the mark of a sith lord! Jedi Genocide! To any "true" star wars fans fans that may read this, star wars is about the story, characters (jedi or other wise) and the fight that goes on between good and evil (like or own world if you are philosophical) and that it shouldn't be bashed! Revan propably would have been a "normal" jedi but this was his destiny so deal with it!
Thanks for letting me vent my anger! I been more and more annoyed as I read this thread! Here endth the lession!
P.S EU does not suck!
