Tyson is the only one on that list to deserve to be in the same sentence as Ali, Frasier and Foreman. The rest, including Lewis frankly, are also rans in boxing history.

Tyson makes #6 on one. Doesn’t make the top 20, top 10 or top 12 on the others. Over-rated.
Lewis makes #7, #12, and #11 and #9. Appearing on all lists.
I’m telling you his stature is rising as people watch the fights and look at the records.
And of course, he did knock out Mike Tyson in the 8th round. (And Tyson is one year younger than Lewis, before you get started with the age excuse.)
There does seem to be universal acclaim for Ali as the Greatest of all time.
Foreman is also uniformly ranked high: 5, 9, 6, 6 on these lists.
Frazier also high, but not quite the equal of Foreman who tops him on 3 of the 4 lists: : 7, 6, 7, 10
And, yeah, I guess your point is “the greats fighting the greats” is shown by this survey, so maybe the Golden Age does deserve it’s name. Sonny Liston is arguably part of that generation, he appears several times, and Larry Holmes is on all the lists and did fight (and TKO) Ali late in his career.
