GGG at the moment, he's far more dominant in his division. But I'm open to AJ changing that in the future.
Your poll question is who is the "bigger" talent. Joshua is a monster next to GGG. Maybe 75lbs and 6" bigger.
GGG by far, Joshua is just some science experiment who does not get tested and has an entire nations boxing board of governors making it as easy as possible for him.
Golovkin's division is an embarrassment to the sport. AJ will eclipse him after he dispatches Klitschko.
