Who would win?

I say Mike Tyson. He had good head movement and could get on the inside quickly and work the body/head with his power. He was a better puncher than
Joe Fraizer who didn't fair too badly against Ali.
Frazier did not face prime Ali, plus Frazier had more heart & stamina than Tyson.

Tyson was too mentally weak to live with Ali.

Ali by late TKO, easily.
