If you wanna go that route of common opponents: Dominic Breazeale "Anthony Joshua's punch is like a slap compared to Deontay Wilder's power".
I'd say Joshua hits about 85% as hard as Wilder, but he is much better at putting together combinations and is the best finisher in the game. Wilder kills you in one hit or he doesn't.
Wilder has more single shot tnt but needs to get back in the ring this year vs a live opponent before everybody forgets this or even who he is.
What's more spectacular a knockout on AJ's record than Deontay Wilder's nuclear explosion on Dominic Breazeale's chin? There isn't one.
In terms of best punch no one that I've ever seen rivals Wilder. That right is just crazy. Seen to every punch in the arsenal AJ has more power imo.
Wilder had spoon fed bums in row to KTFO. To sell him for fans. When he get old uncle Ortiz already had struggled and then supposedly obese and ring rusty Fury schooled him and then beated out of him all crap in rematch in his own backyard.
Everyone in boxing starts off against bums although yes Wilder did fight more bums than them but believe it or not that doesn't change the fact that Wilder has more one punch knockouts.
Wilder is an explosive puncher AJ is more of a thudder with a little speed at times, Just like Wlad. AJ will let combo's fly though unlike Wlad. Wilder is far FAR more dangerous. Almost impossible to get out of the way of his straight right hand when he pin points it. The only fighter in heavyweight boxing who can cover more range over the same amount of time as Wilder is Fury!
