Pit the top 5 heavyweights of the 90's vs the the top 5 from the 2000's vs the 2020's, which fighters from which era would come out on top overall?

 

Holyfield peaked in the 90's and was shot by the 2000's, he was great but very hittable, Fury beats everyone except Usyk and M.Tyson due to his size and speed, Usyk is the greatest heavyweight of all-time, AJ is better than Mercer but has a weak chin so that's 50/50, same with AJ vs Bowe except AJ is more explosive than Bowe was, however Bowe's hooks were far better than AJ's and he threw more two-fisted combos giving him the edge, AJ would beat Bruno and the old, plodding Foreman. Holy from the 2000's loses to AJ, Lewis beats AJ, AJ beats Wlad and Vitali and Haye, 2020's are better than the 2000's.

 

Mercer would be too small to fight 20's giants, M.Tyson would batter everyone except Usyk just due to his speed and fundamentals, he was a freak, Bowe was overrated, Bruno was not world class and would get destroyed in today's era, Foreman would be too old in his 40's to crack the top 10 in today's era.
