Chael by far, Anderson at the time was not to well received coming of his a win with his antics from the Maia fight. Sonnen was trying to play the heel but everyone loved him for it, he represented the American hero and promoted a fight like no one else, no one really knew how well Sonnen was going to do but considered Andersons previous dominant performances, he was a solid underdog. Anderson at the time was considered one of the GOATS.
He dominanted him everywhere for 5 rounds, only to fuck it up within the last 30 seconds. Even though he lost, I think more people had more admiration for Sonnen than they did for Silva at that point...even though Silva's come back was remarkable, he also only had to last another minute or so against Jones and he could of won the LHW belt, I couldn't imagine the shit storm that would of created. He has terrible luck..
Robbie is well loved amongst hardcore, casual and old school fans of the sport. Rory was nowhere near as dominant as Sonnen was, it was a pretty competitive fight but I believe most people were rooting for Lawler, aside from a large majority of Canadian fight fans.
