An uninjured Dorian with a smaller waist would in my view be comparable to Ronnie but still not as good. As it is, I think Ronnie takes it without much problem.
I do think that Dorian had superior hardness in certain areas and fuller and more pleasing lats in certain poses. His lats looked thicker in the front lat spread and had a more tapered look in the front double biceps. The rear lat spread obviously went to Ronnie and same with the rear double biceps. However, I can also state that Dorian had superior hardness to Ronnie in the rear double biceps. Of course Dorian's calves were bigger and harder than Ronnie's, although I don't think anyone was seriously debating that.
