I think the Animated Series was a major factor in a lot of people our age liking the X-Men, whether they read the comics or not. For me, personally, that's my favorite X-Men team (Wolverine, Jubilee, Rogue, Gambit, Jean Grey, Storm, Cyclops, Beast & Colossus).
I feel that the current Avengers movies will shape people's perceptions of that team as well, even though the team is completely different in the comics. Hell, I think some of the MCU Avenger members might be dead in the comics.
