I just used NixOS daily for maybe a month? I really love how it's designed, but I had to give up because there were just so many small fixes I had to do and I found myself banging my head against the wall when I couldn't build something that depended on python-tk. You will see this criticism around a lot, but the documentation just isn't there yet. If you try to search for a fix, the packages have changed how they're configured since a solution was posted or they depend on a Nix flake which 50% of searches say not to use because it's experimental and 50% are all in on flakes.
I have since moved back to Arch, but I've started to use the nix package manager for some cases since you can on-demand non-permanently install a package.
I've been fully daily driving Linux for about 15 years now, and for me it's almost all Arch now.
I started out distro-hopping between Debian, Mint, Ubuntu, Slack, etc, but once I found Arch (and spent two weeks getting it installed, booted, and customized exactly to my liking) I was finally at home.
I know the meme. I'm not here to claim superiority, or diminish the value of other perfectly good distros. I love Debian, I love Void, Ubuntu can die in a fire, etc.
What I love about Arch is the lack of bloat. You get precisely what you ask for, no more, no less. You can legitimately run htop and recognize literally every program, and know if something's wrong immediately.
Every one of my Arch boxes is a perfect little snowflake, suited to exactly the task(s) I built it for. And if there was anything I had to learn or configure along the way? That's just the journey, man.
I have been eyeballing NixOS though...
