I like Nole too, he is my favorite player for some time, beside him I support Ancic and that's it.
Federer is a class for himself, and noone can't be compared to him at the moment, he is winning matches gently with grace unlike Nadal who base his game mostly on his strenght. (did anyone noticed difference between his left and right arm?)
And what about Nalbandian you guys think? He is one of the most talented players in the world, but the thing is that he is playing tennis more for fun and not like a professional. I heard he barely train.
