Can't we get more comparison picks up?
With the two on stage I mean.
"Logical" keeps making straw man arguments.
The fact is Arnold had full AND peaked biceps (Sergio was just full), superior chest (overwhelming majority of people agree), better proportion, better definition. Taken all together, he was superior.
Sergio was a guy with big arms, unusually small waste, and average everything else. Oh, and powerlifter thighs.

Chest, biceps, and shoulders are key bodyparts when it comes to presenting an Olympian "alpha" physique. Arnold exudes this quality. His stage presence was tremendous. He was tall, ripped, and balanced. (Did Sergio even diet?) Olympia grade-A material. Next to Sergio he looked positively giant. I think you could make a better argument for Serge Nubret, but I prefer Arnold. Nubret was more balanced. He was the Shawn Ray of his time. Serge is comparable to offseason Lee Priest or Capriese Murray.
It's amazing, because people were saying Cutler won in 01 because Ronnie's conditioning is off. Yet, Sergio gets a pass for terrible conditioning because he's a "legend" in Logic's mind hahahahaha.
