Ok, I just switched back to the M1 from the 2012 MBA. Keyboard is just too shallow and key travel is just too short. It is improved over the butterfly but it still isn't as good as the 2012.
The machine you mention is my work machine, but it has been docked and I haven't really broken in the keyboard.
The previous work machine which I typed in probably 20k words a day was a butterfly keyboard mac. I hate that machine with a passion, I want to buy it back from my employer and bisect it with a plasma torch.
