No contest.
Arnold is far superior to Coleman.
If he had had access to the same drugs, nutrition, sponsorships and emphasized legs the way they do today, Ronnie would not have one olympia to his name.
Arnold is taller and would be able to pack on way more muscle than he already had.
Arnold always said that he wanted everything to be in balance, to be perfectly symmetrical. "I would not dream of increasing one bodypart by one inch, that would mean I would have to increase my entire body by one inch"
Coleman has no symmetry, he is just a collection of Huge body parts.
Quads overpower calves (which by the way are virtually nonexistant)
Bis overpower Tris
Back overpowers chest
Gut overpowers Hamstrings

Do you honestly believe that if Arnold had access to the same shit that Coleman has he could not increase the size of everyone of his body parts.
He would bring his back way up, already had a lower lat tie in than Coleman
Chest is better 30 years ago already.
Arms, nothing needs to be said here.
Shoulders were always one of the oaks strong points.
Calves.

The only thing Ronnie might beat him on is quads and glutes, but, much like platz, who the hell cares.
