So then it's just a bad Hippowdown?
Donphan has a unique variety of offensive and supportive moves that no other Pokemon can match, therefor trying to find a "better" or "worse" Donphan is simply impossible. If you are trying to imply that they fill the role better, then your statement is again subjective to the team said Pokemon is being placed on. Though given statistics, I cannot argue that Donphan fares better in UU at the moment, but then again, so does Hippowdon.
I can also recommend Mega Scizor as a good bulky and offensive Defog user.
