You do realize that GSP beat Bisping, while Anderson lost to him, yes?
Also, you do realize that Bisping was tied with GSP going into that fight for the most wins in UFC history? Right?
And you do realize that GSP came back after a 4 year hiatus to absolutely merc Bisping. Correct?
You realize that Bisping had a better career, and it's not even close, than Forrest.
Both are journeyman fighters in the UFC. No one will ever try to claim that they were the best in their weight classes. Well, no one with half a brain anyway. But GSPs win over Bisping is every bit as impressive as Andersons win over Forrest.
And if you want to talk about belts being just belts, and it's who you beat, GSP beating Hughes 2x to win the WW belt is far superior to Andersons wins over Rich, and that's not even close. On top of that, remind me who Anderson beat to win a 2nd UFC belt..........
