Miles is a stronger character if he has to follow in Peter's footsteps. Its a core part of the character and his struggles.
So, while I want to see Miles, not before Peter.
We deserve a definitive MCU Peter Parker first, done right by Marvel. The Spider-Man franchise is no going away anytime soon, and Marvel (and Sony) can afford to play the long game here. Imagine the impact of a major death in the MCU, while comic book fans might expect it, the larger movie-going public would be shocked.
