Even this depends on how much you do or don't expect supers to change across media. I can't say my Champions games ever felt like anything but superhero games to me, but I don't expect a game to look exactly like a movie to look exactly like a comic book.
It didn't even feel close to the supers comics, TV shows, nor movies. Given this was in the 1990's... the movies weren't that good.
Advanced Marvel Super Heroes did, however.
Marvel Heroic Role-Play did even better.
Sentinel Comics does it best, for me... but not for everyone.
If I were to start a new group with players I don't know, I'd go MHRP/Cortex Prime.
If I were starting a group for traditional gamers who don't care for new-fangled dice tricks, I'd got AMSH.
If I were starting a group for storygamers, Sentinel. Comics.
If I were starting a group for medieval super-heroes, I'd grab D&D 5E or Pugmire...
