Oh, for the record, here's how they are rated by the people (i.e. voters on IMDb). Collectively, they do the best job overall although
Logan is disgustingly underappreciated. Some of the newest will slide down this list with time. That's just the nature of recency bias:

The above IMDb list is pretty exhaustive even it's a bit controversial with the inclusion of films like
V for Vendetta which was a comic, but whose hero isn't technically a superhero, at least not anymore than Batman is, but who doesn't exist in a superhero universe. Another is
Kick-Ass which, again, technically isn't about superheroes. This list was made in June 2018, so there's a few missing (principally
Joker). If you're going to include
The Incredibles I don't know why you wouldn't include all the other superhero animated feature length films unless you're focusing exclusively on the box office.
Spider-Man: Into the Spiderverse is the best of them all, and it also isn't on this list because it's too recent. Borrowing from him, and sticking to live action, box office, and superheroes, which means omitting even films like
Chronicle about super-powered individuals who aren't really superheroes, or aren't part of superhero comic universes, here are the Top 50 as rated by the people:

*IMDb Top 250 title
I left it off the list, but I must say I'm intrigued by the classic Bollywood title
Mr. India, and I think that's probably one almost none of the viewers of this thread/post will have seen. With a 7.8 it would have been one of the highest-rated films on this list:
