The issue of popularity becomes more tangled when we consider that Marvel is global brand now. I think that in US the "flagship" titles would be Spider-Man and Avengers. Bu for example here i Poland, Marvel comics only appeared in the 90's and the only titles were spider-Man and X-men. Only a few Avengers comics were ever published and even now you can't get current runs of most titles. I have to rely on torrents. In any case, this means that, as far as I've observed, most people from my generation (children of the 80's) know the X-men pretty well and at least know about Spider-Man, but only found out about the others now, thanks to the movies and cartoons.

All in all, I think that for a global brand the best flagship now would be Iron Man, because he is the best known movie character, with Spider-Man as a close second, because he is probably the best known comicbook character.
