Wilder and Shavers were more powerful than Joe and Tyson was more powerful too, his uppercuts were harder than Joe`s left hooks, but his hooks were very hard to evade though.
I'd say Wilder's right hand. Not that Joe didn't have power (he did) but it was the way Joe set up the left hook, making it difficult to evade that was the real danger. Wilder only recently learned to punch straight.
Hmmm, good one. Wilder’s right hand definitely is more powerful but Joe’s left hook was a thing of beauty...to everyone but the recipient. He was usually the smaller guy and it was a punch that was well disguised by Joes bobbing style and physical stature. He was not a large man but that left was so effective. Joe was a much better fighter than Wilder but you can’t discount Wilder’s power. Of course, Joe fought some really good opposition and threw that left against the best in the business. Wilder has made a living crushing cans and fighting very low level opposition. It’s easier to look like a killer against bums. Joe had to do it against guys who could actually fight back. That’s harder.
Joe had to work hard to land that left hook. Wilder can hang back and fire the right from distance. Joe was a better fighter, but Wilder's right hand is a better weapon. Imagine if Wilder actually knew how to box.
