It can be argued that the Warriors of old tended to tap into the gray areas and sometimes downright dark zones in terms of Light and Dark sides. Also, in terms of Saber combat, Revan would have an advantage, since lightsabers were fairly common compared to the ROS and post ANH era's. On the other hand, anyone in those era's who -did- use a lightsaber were always powerful and skilled. Makes for a rather small pool of challengers. Since we can't have them duke it out in a round-robin, we might have to agree to disagree.

As more content goes in, more options will pop up. I'm sure the option to try and patch things up with your companion will be added. Probably with a quest, involving a 'lightsaber' and the need to put it to use. I'm sure it'll have an appropriate end boss or suitably heart warming/crushing finale where you admit it was all your fault for choosing the other girl/guy. Take that how you will though. My Warden enjoys putting his Saber skills to practice though as he so often seems to tell all the NPC's he meets.
