James from metallica, damn good he can hold anything
Nuno in extreme, funky riffs... pretty sweet
Dimebag has an awesome feel in most of rhythm parts
Vai has pretty cool grove too (check cameleon from Billy Sheehan solo CD on live at astoria DVD).
But let's not forgget one hell of a player that does amazing rhythm parts...
Mr. Jhon Petrucci, DAMN I wish I could wirtte rhythm riffs like his (check most of Dream Theater train of tought, his solo album Suspended Animation has great rhythm stuff like Damage control).
And in other direction, I dig a lot into "G Love and the special sauce" groove, dunno why.
Power corrupts. Absolute power is kinda neat.
