Serge and Sergio were awesome bodybuilders..........th at being said,neither were better than Arnold on contest day...........no other time matters and off season doesn`t atter in the least.
Sergio as awesome as he was ,never got into top shape except for 1972 in Essen Germany and even then he could have been harder,albeit,he could have beat arnold on that day with little legit complaints from anybody as Arnold hadn`t reached his peak yet at that time.
As far as Nubret goes,beautiful physique but no legs and this is at a time long before gargantuan quads became the norm.
Awesome upperbody,weak back, and stood with one leg in front of the other in most poses to hide his weak quads.
All told, the three of them look light years better than the slobs we have competing today!!
