My fav is the one and only Lesnar in that division.
Up and coming heavyweight by far is Cain Velasquez (still unbeaten)
Jon Jones is another unbeaten middleweight (i think), incredible style, looks like a dancer when he fights or that dude from Street Fighters who was always swaying and shit when fighting.

I realy like rich franklin for his hardcore training methods,I also like forest griffin as he faught his way to the top after winning the ultimate fighter!
Gotta be lyoto machida, gsp and kongo, quality fighters. the way machida handles himself in the octagon is awesome, so relaxed and always waiting to counter any move, one of the best!
