I sound like I am trashing Claremont. Im not at all saying he was bad, but I do not believe that he stands up as well on his own as John Byrne does. When I judge the quality of their work, IMO its not even close. Byrne's Fantastic Four run absolutely blows away anything that Claremont did. Uncanny X-men was pretty good, but didn't take off and become something special until Byrne arrived.
Thats my opinion.
