lol yeah i'd like to see that too.
anyway, this would be close. zauriel doesn't have too many showings so he's always been tough to gauge. tony has fought lots of enemies capable of slicing his armor, so that's nothing new. not sure why speed was equalized though. does zauriel have some crazy speed showings i forgot about....?
based on memory, i'd say tony would take a small majority. i don't recall any really uber durability feats for zauriel and tony just has a lot of offensive options available. but like i said, i could be forgetting some of zauriel's showings.
