The only linux distro where I've never experienced disruption whatsoever when a new version comes in. A testament to the validity of the approach they are using (immutability). They also have a simple way to package things, and this produced the largest repository of packages of any linux distro. If something works, it stays working, breakage after updating is unheard of. The unofficial motto is "nixos fixes that."
Forgot to mention Nvidia CUDA is now a first-class citizen. Nix becomes a support target for Nvidia. How times have changed, thanks to Google scaring the bejezus of Nvidia by running Gemini on their TPUs. Nvidia may finally get their act together on linux
