Accidentally voted Oscar. GGG destroys DLH. He was nothing special above 147, actually fairly average..
GG only because Oscar was an imposter at 160. Besides that, Oscar is twice the man as GG in every category
GGG is too big for Oscar head to head, and, would win a decision. I don't see Golovkin stopping Oscar. Overall, De La Hoya was a more proven fighter, and, should be ranked higher in all time status.
I was going to write something similar. WW or maybe even LWW was De La Hoya's best weight class. Even at 154 pounds he didn't look particularly sharp. I still rate DLH higher though in a P4P sense and I think he accomplished more in his career. But H2H with GGG, he loses probably by late round stoppage.
