Sexy, what you don't seem to get is that there's more to power than just knowledge. Until Ragnos has some concrete stuff on him, you just can't consider him more powerful. You can deduce that he's up there, but not that he's more powerful.
And it's funny how you give Revan the best chance of being better, when he's quite clearly the worst on that list. And don't try to pass Bane off, the guy pulled a fricking moon out of orbit, I've proven this, here, I'll post it again:
My argument: Bane pulled the moon out of orbit.Premise 1: Bane planned to do so, and fly on top of a beast from Dxun to Onderon.
Premise 2: It's later confirmed in tNEGtC that Bane did fly on top of a beast in between their atmospheres and that he did meet up with Zannah.
Premise 3: The two atmospheres had slowly been moving away from each other for thousands of years, by this point they were too far apart for Bane to travel across, so the only way Bane could have travelled across them would be if the atmospheres somehow were close enough together, and the only way Bane could have ensured this is by pulling the atmospheres close enough together with the force.
Now you can whine all you want about me not proving it, but until you can either prove one of those premises wrong, or prove how those premises don't form the conclusion I arrived at, you'll have to accept it.
