I don't think so - he did kill all those Jedi in that fight with his lightdagger, Force Lightning, and such, but Revan was more decisive in his fights - at least, when he realized his true power, as when he fought in the battle up in the Star Forge, he just killed, no problem. Ukan was impressive, no doubt - in fact, he seemed stronger than Pall through most of it, but I think Darth Revan is simply a little bit too much. Exar Kun fought off masses of Jedi all at once, but he still, I think, would be destroyed by, for example, Marka Ragnos.
