Bradley vs Hatton is close. Ali in his prime (64-67) vs. Tyson in his prime, not really all that close. Tyson was very very very similar to basically a 1980's version of Sonny Liston in the early and mid 60's. Similar height and build, as well as styles, and fear factor. Ali had way too much speed and one of the most accurate jabs in boxing history. And Ali could take a punch. Once the fight got past 4-5 rounds and Tyson knew he couldn't get Muhammad out of there, and after eating jabs and quick combos from Ali, he'd wilt, far worse than he did against Buster. Ali by TKO stoppage in the 10th or 11th round.
With that said, Tyson is an ATG HW, and H2H, I'd pick Mike to beat probably 85-90% of the great HW's. Ali in his prime was just all wrong for him.
