I upgraded from an M1 pro to an M3 max. it's a nice upgrade.
My 3000€ i7 mbp16 2019 recently died and I replaced it with an "interim" base model, 650€ MacMini M2. The jump is huge, that freakin Mini beats my 3yo (I bought it in 2020) decked out MBP that constantly spun fans. While intended as Interim until M3 MBPs where announced, I see no reason to upgrade right now.
