Pre Kotor Revan I cannot gauge, since I believe he was masking his true power from Malak like Sidious was to the Jedi. Kotor Revan would lose, but he would kill one of them. Post Kotor cannot be gauged, Kotor III will hopefully show Revans full power, which I am dying to see by the way. But, by they way Kreia described him and so on, Im kinda willing to say Revan would own those two in his Post Kotor form. But im not really sure, so Im just gonna use Kotor Revan, he loses but kills one of them.
