I have nothing new to bring to this thread, and I think you can easily say their levels are all very similar...
But when I review the fight Jman had with Pain and the level of raw power and skill displayed by Jman it causes me to ask myself if either copy cat or guy could have survived as long or do as well, and my answer is always no...
So yeah they are all close in power level but at the end of the day my bet would always fall on Jman over either Kman or Guy...
PS
And so by default I think the Sannin are all on the same level so my bets would be with any of them over Kikashi or Guy. Even though they are all (Sannin & Guy/Kman) on higher levels than the masses in the naruto universe...
