It’s mostly personal, I’d wager. And what one is used to.
I’m a thin wrapper person. But boiled dumplings need a thicker skin than steamed. So do I not like boiled dumplings? No, they’re just in a different category in my mind. But I have compared har gow and shumai across places based on the wrapper and the flavor and quality and quantity of the filling.
I agree on buns, but for a slightly different reason — the filling to bread ratio is the inverse of what I like. But people love them!
