Which level 7 creature is the best, and why?

Well, I did say it, but no one believes me. Regarding the Archangel, I can only say that he is the strongest. Losing 1-on-1 doesn't mean anything; even the computer considers him the strongest. But we also have a small dispute brewing about the second place, specifically in 1-on-1 hand-to-hand combat. I say it's the Archdevil, but again, no one believes me. I'll have to post a video to prove it.
