Not nearly as much. I never particularly gravitated to Iron Man in the comics that much, partly because of his whole militaristic, Cold War, capitalist, Howard Hughes origins, and partly because I never really found the secret identity/heart condition/addiction side resonating with me. And especially in recent years, he’s really been written as an awful person.
RDJ did a lot with his charisma to make the character more interesting and relatable, but there was always stuff in the movies that really didn’t get explored enough: the whole “privatized world peace” thing from Iron Man 2 got sidelined after HYDRA popped up in Winter Soldier (I don’t like the idea of billionaires running their own military policy, but I don’t want HYDRA getting their hands on Iron Man tech) but needed to be worked through more given what happened in Age of Ultron and Civil War, etc.
Finally, I guess because of Marvel’s smörgåsbord of characters, I’ve never really need to relate to Iron Man that much. When it comes to sciencey heroes, I’d definitely identify with Peter Parker over Tony Stark.
