His direction and vision has more to do with the greatness of that franchise than any of the actors.
RDJ on the other hand IS Tony Stark. The personality we have grown accustomed to with these two movies is almost irreplaceable. I can't think of a single actor that can hold a candle to RDJ's Stark.
