Dorian gets my vote. Sheer mass isn't the same as refined class; not that Dorian had a physique that was much nicer to look at. It's very simple, he brought a level of conditioning/hardness to the stage and hasn't been successfully and consistently replicated since. Ronnie is just someone who gains muscles upon muscles, but overall he looks disgusting and a poor representation of Bodybuilding. Ronnie's only lasting tie to a legacy in BBing is his gut.
