The record book will show that Yates defeated Coleman and all bollocks aside that is all that will matter in time. Coleman is a freak though and easily the most genetically gifted to grow muscle bodybuilder ever, but his structure is something overlooked by many guys here, and as great as his hamstrings were from behind, mostly as they were so defined, from the side in comparison they lacked overall depth and tie in when compared to Yates. Yates in 93 could beat Coleman at his best in nearly every compulsory pose, the side poses he would take as he had better legs from the sides, hamstring flow, and from the rear it was close but the calves pull it out for Yates. The front ab pose he owned it before his gut blew out post 93, and the front lat spread the same, i would also give him the front double bi in 93 as his bodies overall flow and taper beats Ronnie's structure, only as he has those overly long arms and legs with torso deficiency in comparison.
Bodybuilding is the sum of all parts structure and symmetry included, if it was only about muscle and who had the most Ronnie would win but it isn't.
