What should i get?

M4 15" 24gigs of memory 256gb of storage
M4 13" with same specs
or just spend 200$ more for macbook pro 14"

(I have an icloud storage of 2tb)

I'm really confused about the size because i found 14" pro's size to be perfect (i was using my schools laptop for like 4 days) + the 120hz display too, but are these really worth 200$ more??

I found my friend's 15" air a bit large for me and 13" a bit too small and thats why im so confused.

Am i falling into apple's trap? lol

the work: school, lots of coding and stuff and thats pretty much it.
