Interesting. I agree with you about being most comfortable with a desktop/keyboard interface, but have the exact opposite opinion regarding macs.
IMO, OSX is the perfect platform for a keyboard-driven power user. It's unix/BSD based, so software works mostly the way you want it to, but unlike Linux it "just works" without endless fiddling. I don't use the OS UI much at all: Spotlight lets me open any app with a few keystrokes. All my time is spent in the terminal or the browser.
I've done almost no fiddling on NixOS in the last 7 years. People fiddle on Linux because they like to fiddle. My experience is it absolutely Just Works. By contrast, I've had OSX at work delete my data after one update and corrupt its install after another.
