Marvel's A-List, as in known by non-comic book-readers, 10-15 years ago were Spider Man, the X-Men, Hulk, and the Fantastic Four, more or less. I think the non-Hulk Avengers were the bottom of the A-list for Marvel comic book fans, but not very well known by pop culture at large. It is frankly amazing how quickly Disney made the Avengers household names.
