I think Upgrade could defeat any alien that can't become intangible with that logic. Assuming we don't count the Omnimatrix as a factor, though, I would have to say Upgrade has the advantage still. Upgrade is great against enemy groups. I can't think of one thing Ditto could do to take down a Mechamorph.
