Meh Vader was a crap sith lord
He might as well be swinging a baseball bat instead of a light saber his movements are so slow
I cant believe he got beaten by luke, it was pretty even with the slow 360 degree movements that took about 10 mins to do :D
Revan was an OK sith Lord but in a fair fight Nihilus would of beaten him, The Exile got lucky agains't him
