Did I specifically say i was referring to Marvel only? You said there is no sense in 'sculpting' pants to look like pants when you could just use 'real pants'.
I think marvel is actually one of the more forgiving PF lines BECAUSE of the costume designs that are mainly spandex.
But if youre saying that cloth pants, shirt, or jackets at 1/4 scale or even on a 1/6th figure will look better and more dynamic than purely sculpted pants, i'd have to fully disagree with you. With fully sculpted pieces, you can get the exact fabric folds that you want, given whatever dynamic situation you want to be in. such as a wind effect, etc.
That is the same thing as saying, "why sculpt hair when you can actually use real hair?". because 99% of the time sculpted hair will look more natural and dynamic than actual doll hair.
And for the record, as great a piece as Thor PF turned out to be, I actually think that it would have looked way better had it been fully sculpted. Something about his costume just doesnt look up to it's full potential. and some people say it looks too much like an onesie. Even Cap and Hulk, looks great and is one of the better PFs, but if youve seen the pics of those bootleg recasted Cap and Hulk PFs fully sculpted, you'd agree that they look superior to the cloth ones.
EDIT:
Foud the pics
There is no way you can tell me those do not look better than the PFs with actual cloth.
