Arch Linux. Always very up-to-date and the AUR is huge. No dealing with PPAs or snaps or flatpaks or appimages. Just paru -S any-software-ever-made. Also very streamlined (systemd for everything lol) and well documented. I tried NixOS for a bit but it was very inconvenient in comparison and I felt like it was impossible to tinker with or understand if you weren't good at Haskell. Terrible documentation.

You don't need any haskell knowledge to configure a NixOS system. It's mostly just researching the right options and setting the desired values. Pretty simple. For more advanced stuff like custom modules, functional programming experience helps a lot but that's not necessary for installing packages and enabling services.
The declarative abstraction of just setting values of options is very nice but I quickly ran into many edge cases where it leaked, which have been fixed years later. Obviously I don't want to wait years but I couldn't figure out how to fix it myself. I was able to overcome the learning curve of all the various hyphenated CLI programs (seriously what's up with that), how home-manager fits in, basics of the nix language, etc., but got stuck at trying to learn nix well enough to actually contribute.
There's a huge barrier in straying from the well-trodden path, and I think that path will always be behind the cutting-edge. In traditional distros I just have to install something or edit a text file somewhere. Prime example right now is pytorch with rocm support. In Arch Linux it's pacman -S python-pytorch-rocm. In NixOS I barely remember and I don't think it even worked for me but I think it was this: https://github.com/nixos-rocm/nixos-rocm#installation
I started using dotdrop to track and manage my user and system configurations and wrote a basic ansible playbook for my desktop install setup which has achieved 90% of what I was looking for in NixOS. These days what intrigues me about NixOS is that it might be a great alternative in the server space as a competitor to using docker or wasm.
