I think Dillet's were better.
Just as big, with better shape.
Having better shape than Yates wasn't the hardest thing to do 
IMO Dillet's legs are right up there with the best ever.
I think it was the 96 GP where Dorian was "sick", yet weighed 245, and Levrone looked better, Dillett was a giant.
Apparently, Dillett didn't squat for his legs, he did everything but squat. Had a famout article in Flex about not squating.
