Best Coming of Age musical

Inspired by another thread on here - what's your pick for the best coming of age musical? A few suggestions to get you started:

Heathers, Dear Evan Hansen, Be More Chill, Kimberly Akimbo, I suppose Mean Girls fits the theme.

I submit Rent doesn't count (they're too old/that's not really the focus) same for West Side Story (there's no real maturation of the characters here). But as always, you may disagree.
