Lots of interesting takes on a question we must all ponder when buying.
I confess that I probably over-spec'd my 16" M1 MBP as upgrade on the 15" mid-2015 MBP.
I bought the mid-2015 MBP in 2017 because I didn't like what I read about any of the later Intel models & their keyboards. It served me well, and when I upgraded to 1TB I kept the other SSD with its older Mac o/s as that had means to run some Windows-based software.
But the 16" M1 was exactly what I was waiting on.
I treated myself with some readies on the M1 Max'd out with 32GB.
This has the occasional grunt I need for some statistical work and for my bad habit of having lots of apps and browser windows open at the same time.
The only downside for this desktop equivalent is that is a noticeably heavy luggable, hence the purchase of a s/h 13" M1 MBA. Again I probably over-spec'd on current needs as I hunted and bagged one with 16GB.
What I conclude from this post hoc reflection of behaviour is that I have bad habits, am swayed by 3rd party reports but I don't like the hassle of frequent upgrades & resets with my odd collection of apps.
PS I had earlier tried and failed to use a probably over-spec'd iPad Pro w/keyboard as a travel substitute for the larger MBPs.
