All I want in life is a Linux distro with a package repo full of meticulously reworked & reconfigured packages that make all the keyboard shortcuts across the entire system and every application be like and be as consistent as my old Macs. I've been full-time Linux (Kubuntu) for a few years now, and I've hobbled together something that only irritates me to death about 30% of the time rather than the 100% of the time…
NixOS, by accident or intention, inherently circumvents this problem. It also has actual non-existent UX: you need to manage your own home-manager configs (for now, I want to change that). The maintainers have put good effort into being able to express tons of preferences in your nixfile (to the degree of Firefox plugins).
You may get nerdsniped by it.
