Nick compared to Hunter is on another level as far as nasty, freaky development goes. There is a bunch of oil, varicose veins, slightly short legs etc but the freakines factor is something to consider. If I have to bet I say Walker beats Hunter at the O. Walker also put a shitload of pressure on himself with the pretty delusional predictions. His arms are jimmied up something crazy but still looking comparatively ok, just insane size.
It's like why did Branch Warren ever place high with such an ugly physique, even 2nd at the O? It was because of just a nasty level of freakiness and muscularity. Same with Walker.
