In the process of moving over to NixOS right now. It's been fun, but I definitely sometimes hit a wall where I don't know what to do and it takes me a while figure things out.

I was using fedora before which is great too, and I've used most of the other ones in the past as well. I'm making the switch because I want using my computer to feel more like a hobby
