i would say season 1 just because of the talent that came out of it but on a side note i think diaz would have won the final b/c he had bad first rounds in most of his fights on the show but go subs in the second and he did bad against hill but got him
I never really watched season 1, but they do have the best fighters right now. That might also have to do with having more in cage face time since the start of the show. Entertainment wise - season 3. Season 5 was good but had a lackluster ending due to the injury.
Season one was probably the best.
Season 2 was dogshit due to the fact that Eli quit before it even started, the one WW didnt make weight so he got eliminated, then Kerry gets injured and leaves, then Burkman gets injured and Von Flue came in. Not to mention nobody could finish a fight. end rant...
Season 3 was ok too because of the coaches.
