Ultimates! Tony seems to be a fairly live and let live guy, which is why I like him. Ultimates Stark knows that he's incorrigible, but unlike Ultimates Steve, he doesn't hide behind a flag and principles.

Actually, Loeb give us a nice slashy S/T moment in Ultimatum, although the rest of the series so far has been horrendous (let's just say, it has not been a good year to Jan Van Dyne in the 616 and Ult universe).
