He certaintly is up there on the list. I would probably say my "favorite" is Sugar Ray Robinson. This guy fought more fights in 2years than most pros do in a career. He finished his career with 200 fights 173-19-6 with 108 KO's !!
As far as tough goes, there were none tougher than the Rock. Marciano had unbelievable heart and a fabulous chin.
