What's up.
Revan:
Revan could augment his strength, speed and enduance with the Force and perform various acrobatics.
Revan had a powerful Force Sense, being able to sense someone from across the galaxy
Revan was able to use the Force to heal his wounds without medical attention
Revan was a powerful user of Telekinesis. He could use push, grip, choke and could crush his targets.
Revan was very proficient in his use of Force Lightning, and used his bare hands to absorb and deflect powerful lightning attacks.
Revan was gifted with Farsight and could use battle precognition.
This is why I say in a contest of Force abilities Revan would defeat Obi Wan. I still say it's a toss up as far as a lightsaber duel is concerned. It's stated that Revan "Learned all of the arts and ways the Jedi had to offer" but it doesn't specifically state that he mastered any lightsaber forms, but it doesn't say that he didn't either.
