I've got Fedor and GSP neck-and-neck. Fedor's got the longer resume, but one could argue his last notable win was against Mirko almost four years ago. Quick wins over Sylvia and Arlovski were nice, but each of those guys were a couple years past their prime.
Meanwhile, since Fedor beat Mirko, GSP has gone through a who's who of the welterweight division. Dominated Sherk, Penn once, Hughes twice, Koscheck, and Fitch, and put up some impressive wins over guys like Trigg, Serra, and Parisyan, second-tier guys Fedor has been living off of these last three years or so.
GSP does have those two blemishes, though. I tend to discount the loss to Serra, because that was a fluky hook that caught St. Pierre on the back of his head as he went for a takedown. The armbar is more notable, but considering St. Pierre was winning that fight until that point, and has since cleanly dominated Hughes twice, I don't think it detracts too much.
If GSP puts up another impressive win over Alves, I think that's what'll put him ahead of Fedor in my mind.
