Joshua was the better fighter. And has the better resume. But I do think, stylistically, that a fast and confident Wilder would land one of those bombs at some point, and end the fight by KO
Relatively uneventful four rounds. Joshua gets caught in the 5th and ultimately gets pulverized. As deficient as Wilder was, AJ didn't have the means to beat him. And that's despite AJ having superior boxing skills.
