i’m all for peter being portrayed as a teenager bc that’s just classic spidey, and if you prefer him being portrayed as a teenager that’s fine we all have preferences. my only issue with it is that people who only watch the spidey films and don’t read the comics are really missing out on some good adult peter moments. like right now in the comics peter parker is around 30 years old and watching him interact with younger superheroes is really heart-warming, because he’s been there and he gets how hard it can be, he feels responsible for these kids
and then there’s the renew your vows comic where he’s an actual dad married to mary jane, and they have a daughter who’s named annie may. and that series is full of really fun stories, plus it’s interesting to see how peter juggles being spidey and being a dad/husband and how those two things intertwine, also the dad jokes are endless
teenage peter parker is a timeless version, but that version is shown so much (especially in film) that it seems like a lot of spidey fans feel like adult peter wouldn’t be as good or true to his character which just isn’t true, so if you’re ignoring the adult version of peter parker then you’re seriously missing out on great character development/stories that show peter’s journey and his character more than anything
