They have some things in common: very talented and dominant fighters in their best days, but lacking in terms of resume. Each ot them also won world titles in the one weight class. So, rank them basing on: A) abilities (who was better fighter at his very peak); B) resume (official wins) - Naseem Hamed - Kostya Tszyu - GGG
1.GGG A. ATG chin, top KO ratio in MW history, murderous power, great technique. Longevity, as champ for 12 years or so. B. Canelo, Jacobs, Chenko, Ouma, N'Damm, Stevens, Murata, Rubio, Brook, etc. 2. Tszyu 3. Naseem
I'm sorry, I misread your post. Obviously the Prince is the worst, but those guys would kill for his speed and agility. And power. I'd say : Tsyu GGG Prince
1 GGG 2 Hamed 3 Tszyu Tszyu in his peak lost to Vince Phillips and his resume is on the same level of Hamed's despite Hamed not being liked. Tszyu has better fundamentals but I think H2H Hamed is better at his respected weightclass than Tszyu is.
Why is Prince the worst ? Tszyu's best win is Zab Judah and he lost in his prime to Vince Phillips. Hamed actually made more title defences than Tszyu and regarding their opposition theres not much to choose between them. Hamed's only loss while being slightly past his best was to Barrera who is a great,Tszyu as I said lost to Phillips in his prime who is far from a great and that's a pretty glaring loss on Tszyu's resume.
