Wilder, he literally has no other ability other than power. His jab is non existent, his defense is horrid, his stamina has much to be desired, his chin isnt amazing, punching is wild.
Stamina? He's never gassed like AJ of Vlad. As far as HW's go, he has the best stamina. That will likely change once Usyk gets his first HW fight un open era his belt.
Clearly don't watch how he fights, because he's got a better jab than most current heavyweights and has never completely gassed out in a fight and his chin cannot be questioned since he's the only one out of the top 10 heavyweights who has not been dropped in a high lvel professional bout.
Wilder has speed, power, isn't stiff and can actually hurt his opponent on the inside with uppercuts It's one reason why he was able to successfully land on fury and knock him out, whereas Wlad struggled to land a glove on Fury full stop.
