Holyfield KOs him. Holyfield was way bigger and more durable, it's not even close. Sure, he was those things due to being roided to the gills, but that's another story. He is puny in conparison to other ATG HWs. It's not like I am comparing him to me.
I don't remember that, do you have any evidence? Way bigger? He's notably taller (6 cm), but nothing extraoridinary and his reach is almost identical (5 cm difference). I guess he is slightly bigger, but definitely not "way bigger". About weight - peak HW Tunney weighed around 190 lbs, Holyfield was the best around 210 lbs at HW so the difference is notable, but not extreme. About durability - you don't know that. Holyfield was stopped a few times in his career, Tunney was never stopped. We don't know how durable Tunney was, because he never reached his limitations. He is not puny compared to Holyfield.

Walcott looked very big and Louis was still top 3. The computer showed what would have happened and tend to advance rather Ali, because he was more present (but still got knocked out), that was from his very best, if his own one from 1970 onwards would have stayed in the ring, it would have been more one-sided and the knockout could have come earlier. Marciano had a much better chin and stamina than both, also at least comparable power (I think he hit a bit harder). As the other two got counted out, against not so big punchers, but nobody could make The Rock to stay down. Well Johnson is most tricky and can make it for everyone difficult to land, even when his opponent was over thirty years younger, he made whom to miss. He has a much better general ringship than Louis, particular defensive. I don't think Tyson was faster, as Tunney was much lighter as had the same speed as Carpentier. He is the quickest heavyweight besides Patterson. He was also the most silky boxer in Heavyweight and can outbox everyone. Dempsey was comparable with Tyson and lost twice comfortable, although he had a higher output and more condition than Tyson. I think Sanders would be against every current heavyweight favourite, besides of Usyk maybe.
He did in 1967 or 1968 (in the animated one, by computer) and the press/ media wanted Ali to win it, because he was still active/ recently.
When I do overall ratings in terms of h2h, my evaluations include stylistic matchups and intangibles such as ring IQ/heart as well, not just how flashy they look on film in highlight reels and their measurements.
