I upgraded from a 2019 16" Intel MBP to a 2021 M1 16" MPB. Everything is much, much better, except that I miss the touchbar. It's not that I found the touchbar super-useful, but it was a lot more useful that the fixed set of function keys. An example: it was so easy to take a screen shot. And I could easily adjust the brightness on both my external monitor (LG 5K) and built in display. With BetterTouchTools it was even more useful. I never understood why the touchbar was to hated. Certainly not a giant step in UI, but a moderately useful invention.
