Aright. So he was defeated by four Vong Slayers, while he was tired. Okay. . .
Luke owned seven, eight Vong Slayers, while Jacen and Jaina took one apiece. And this was after they'd fought through the mothership, after they'd slaughtered dozens, and for Luke, hundreds of Vong warriors. Granted, this new information is more realistic, but still puts Kyp a good deal below Luke, and not that far above Jacen or Jaina. The two of them were able to hold off two or three Slayers at a time, while Luke took the brunt of the attack. And when he finished with his, he pwn3d the others.
Face it. Kyp is good, but he'll never be Luke.
You have to put it more into perspective though. Kyp had no idea what to expect. Remember that these guys used longer amphistaffs then had ever been seen before. Luke, Jaina, and Jacen all knew what to expect from these guys. Also note that Luke has a shard of the Kaiburr Crystal in his lightsaber which makes it burn much more powerfully then a regular lightsaber(an more effieciently too). The biggest problem with defeating Slayers was because of their thick armor that Kyp couldn't cut through but Luke could.
You still haven't explained how Kyp can be weak if he controlled a black hole just like Luke did and killed the Leviathan with, according to second_coming27, force lightning.

Revan was able to defeat a really powerful Sith who was able to regenerate his health multiple times. That is a minor thing Revan did and Kyp never did anything as great as that.
Who is to say Revan didn't regenerate from the Jedi too?
BTW, defeating the Leviathan and controlling a black hole are FAR more impressive than anything Revan has done.
