Yeah, and Revan plundered everything he could about the Jedi and the Sith. Add that to his enormous potential, immensely powerful will, and that he is an amazing combat strategist, and you have a very powerful fighter. Plus Yoda is 900 years old. If he was in his prime, then this might be different.
Darth Revan had immense control of the Force before and after his memory wipe, he was even considered stronger after his memory wipe when his power returned greater than before. I reckon he was stronger than Master Vandar at the time and I considered Vandar to be Yoda's match in strength. I think Revan carries victory.
Yes, Revan was trained in a time of war. He was trained shortly after the war with Exar Kun, he fought in the Mandalorian War for the Republic, and then he turned on the Republic, ressurected the Sith, and conquered the galaxy. Countless knights fell in battle, and far more swore allegiance to Revan during this time.
Where does it say they leave after a few years? They can come back as often as they wish, if they wanted. Sure, Obi-Wan's spirit eventually leaves Luke, but that doesn't mean he couldn't come back.
And if there were tons of these Jedi Knight Lights, Yoda would have already known about them, due to him being one of the wisest Jedi of all time.
