Revan vs Corran Horn

My original post was a counter to another user, using that to say Revan > Nihilus.

Right, but I'm just saying I didn't make that claim. I don't think Revan's more powerful than Nihilus -- or, at least, I don't think he can replicate his planetary drain.

Revan can use an extremely powerful drain, but not near Nihilus’. Revan is more powerful in most other ways though, and would win a fight.
