I think AJ has the better resume, alone because of the knockout against Wladimir but is he also the better boxer? Yesterday he showed that he can actually box very, very good against another elite opponent.
GGG is WAY better. GGG is one of the most dangerous fighters in history at middleweight. Now that Canelo tested positive, I lost respect for Canelo because he was likely on something the first fight. One thing Canelo is bad at is stamina. I figured he moved too much the first fight, but he managed to maintain that pace. Maybe, it wasn't a natural pace after all. Problem is that GGG prob only has a few years left. Joshua is young, but he will have to avoid Wilder, Ortiz, Miller, Fury, and possibly Povetkin, or he will be knocked out. Who will beat GGG like that?
Joseph Parker did nothing special and Anthony Joshua just followed him round the ring. If GGG was a heavyweight he would've gone for and got the KO. Joshua is effective but is very basic
