@jashro44: Sorry it took so long (you know how it is)
In closing I'd just like to point out that Iron man has the most going for him in this fight. He is faster, much more intelligent, highly adaptive and on top of that has an arsenal of tools and extremely powerful weapons. Hulk is stronger, but Iron man is no slouch in the strength category, thanks to his suit he can hang with the likes of Luke Cage and Namor among others.
Here are some assorted strength feats:
All in all I feel Iron man has what it takes to defeat Hulk.
@jashro44: No need to apologize friend, it happens to all of us.
Anyway, I don't have very many books featuring Namor so that particular scan was borrowed. But judging from Beta Ray Bill's reaction to the punch it was quite powerful. But who won is irrelevant, I'm simply trying to showcase Namors strength (I think I have sufficiently done that) to point out how durable Tony's armour is.
