Nelson was more dominant over his prime, and over better guys. From a textbook standpoint, I guess McCallum was prettier to watch, but while McCallum was jack of a trades, Nelson was a jack of all trades plus he had fight-ending power in either hand. McCallum had better longevity, but I always ask myself who was better in their prime - for me thats Nelson.
mcallum was just way more skilled. definitely better imo. shame he didn't get a shot at any of the big names in the 80s.
McCallum was not "way more" skilled than Nelson. Thats a ridiculous statement. Moreover, Gomez and Fenech were higher caliber fighters than anyone McCallum beat.
