It's really incredible just how well Endgame stuck the landing, but the whole MCU is impressive. Even the worst films of the MCU are still totally watchable, just forgettable. And comic movies are really easy to get wrong, that same decade of MCU movies overlapped with both Andrew Garfield Spiderman movies, and a smattering of forgettable or outright bad DC comics movies.
That Rise of Skywalker and the final season of Game of Thrones came out in the same year helps to contrast how much most things don't stick the landing.
I really liked Infinity War and have re-watched it a couple of times.
I watched End Game in the theatre and have not seen it again since. I really didn't enjoy the whole "goofy time travel" aspect, and re-visiting all the prior movies/events.

It is certainly more comic-booky than some of the other MCU movies and the acceptance of that will vary from person to person. It also isn't a completely unique concept. They basically stole it from Back To The Future 2 which was also a big hit.
Also it doesn't hurt the MCU's legacy that there is the obvious comparison with Game of Thrones that magnificently failed a very similar task the exact weekend that End Game came out.
