Usyk has the best record at cruiser. If moving up and winning heavyweight fights counts as a part of cruiserweight achievement, then Holy still has an excellent claim, although there are a number of asterixs by it, such as the age and decline of the fighters he beat, PEDs, losses, illegal tactics, not dominating the era, etc. Nelson, Gomez and Huck has long reigns, but beat very few names of note.
Usyk. Holyfields era had no competition other than his fellow countrymen. CW had come of age by Usyks time.
Maybe not the best but worthy of recognition are mormeck and Bell who unified 3 titles when that was enough to be considered undisputed and the first fight was a little talked about classic
No one is even close to Uysk's accomplishments at Cruiserweight. He literally cleaned out all of the top fighters from his era. Gassiev, Breidis, Huck, Glowacki, Mchunu were all world champions.
I love Holyfield and he was a monster at 190 lbs, but the division was a baby during his time. Usyk’s had much better depth. And the OP should receive a permanant ban for not havlng Adamek in the poll. Also, Toney who I also loved had like 3 fights at cruiser, one of which is his loss to Lebedev in his 40s. It can and probably should be argued that Wlodarczyk, Lebedev, Gassiev and maybe even Hernandez are greater cruiserweights than him as well as a couple of other guys on the list.
I think Holyfield still might have the best single win at the weight (Qawi 1), but Usyk's wins over Gassiev and Briedis aren't that far behind and by virtue of sheer breadth of work he's probably got the top spot locked down right now. Or, at least, he's the 1A to Holyfield's 1B.
Yes missed Adamek, he didn't have many fights at cruiser but should have been included. The poll has limited entries so impossible to include everyone.
Don't see anyone beating Usyk. In theory it's do-able but hard. His workrate at cruiser was just too high for anyone to handle. Sure people will always run to the tight Briedis fight but that's unfair can do that for almost any boxer.
