I agree that CC > Dex. While Dex is a great bodybuilder, it's strange that he has a Mr. O and Flex, Ray, Levrone, and Cormier don't. I guess it's all about the era in which one competes, e.g. no Dorian or Ronnie to compete against.
Cormier doesn't have any "freaky" bodyparts which is why he may appear to be lacking something. However, IMO he has just as much of a wow factor as Ray, Flex, or Dexter.
