I'm going to have to agree with TKA-001 here, and say that there's not enough info on either characters (especially Revan) to draw a definitive conclusion. But if I had to guess: Revan. He is the most overpowered and overrated SW character out there, along with the Exile.
But in all seriousness, though, it would be more likely that Anakin would win based on Lucas's statements.
