Ranma might have its genderbent element, but it makes it clear in no uncertain terms he is a guy, thinks of himself as a guy, and his female form is either a curse or a weapon in his arsenal. Even the author told anyone trying to think deeper about it "I don't think about things like that and you shouldn't either."

Compared to others, its far more rigid about where it stands on the matter, and truly is treated as just an extra avenue for gags rather than the centralizing element. I agree on them all being unstomachable.
