Depends, Revans more powerful then both but they work well as a team, but i'm sticking with my homeboy Revan because anakin isn't very smart hell revan could probably turn him and watch him fight obi and then kill the winner, or he could just overpower them both as anakin never reaches his full potential in rots
Anyways...
Obi and Anakin are a damn good team, an incredible team but even in Rots they are far from perfect. Dooku still manages to own them, he didn't expect to lose from Anakin because Sidious told him to kill Obi and then let Anakin fight. If Dooku can do it, Revan sure as hell can. Anakin and Obi are probably screwed.
Especially with this battlefield which makes it incredibly hard to work together well
its ok wht revan just out of curioserty male or female
Either, neither, both, whatever. Revan's gender is whatever you, the player, wants it to be. It was never decided which gender is canon, only that KotOR's ending was Revan making the Light Side choice. There's a few arguments for either side, but none of them are substantial enough. As my Revan was male, that's how I refer to him.
