ND has said on record at ironage that Frank was the better bodybuilder than Shawn.
The only thing Frank had over Shawn was height lol.
And three Sandows

and better balance & proportion , Shawn has heavyweights biceps/triceps coupled with a middleweights torso , he has huge squared-off quads and highcalves , Shawn was thicker than Zane , but thats to be expected when Shawn is 5'7" and weighs 20lbs more , so there you go

thats why one is a three time Mr Olympia and one is a three time runner-up !!
