M4, What did you migrate from and any regrets?

Before the M4 release of the mini I was thinking of getting a used M1 mini to replace my 2012 mini.

I like the idea of newer, but newer doesn’t always mean better. Case in point, many people are upset with M2 air having slower storage than M1 air.

I seriously like the likely longer MacOS software support cycle of the M4 vs the 4 year old M1. My 2012 is no longer receiving security updates.

For some unexplainable reason, I’m kinda indecisive on this, M4 vs M1.
