The idea that anybody could be Spider-Man is a quintessential characteristic of the core of the character, you can be rich, poor, black or white and still be Spider-Man, even Stan said that's why he wears a full face mask, so it naturally follows that he is the best legacy heroes ever created.

I feel like the point of Spider-Man is that anybody can be Spider-Man. Miles and Peter are different characters with their own upbringings. It’s not the same for Batman. Bruce Wayne IS Batman. Only Bruce can really understand what it means to be Batman on a more intimate, personal level in my eyes.

Honestly I believe that Miles is the best example and most successful example of a legacy character ever, in just a little over a decade he has been in animated TV shows, animated movies, and video games, and now a sizeable part of the fandom considers him THE Spider-Man.

Bane would probably fit the tone/stylw of the universe better, but he has been done in live-action movies twice already.
