Both. I have to use windows at work and I hate it.
I did a little bit of distro hopping: Mint, Ubuntu, Manjaro, Arch, Guix. Now I think I finally arrived at Tumbleweed, no need to hop somewhere else so far.
But I really like the concept behind Guix, it's just not finished enough.
I'm studying nano science right now, I think it still exists. And if it does it's still a super amazing thing.
Whenever somebody recommends NixOS, I just want to spam the comments with Guix. I prefer configs I can understand, and I think lisp makes that easier. Other than syntax, the only thing I see is people complaining about the free-oftware-only. But the recently hyped distrobox solves that (together with the nonguix repo). Yet nobody recommends guix in all these "immutable" distro threads.
In my opinion Guix is the best mix of:
Arch (rolling release),
NixOS ("immutable", atomic updates , rollback, reproducible, declarative configs)
Gentoo (source code based, write your own package definitions for any source code you find),
with some lispy syntax.
If you want to try OpenSUSE Tumbleweed without all these weird defaults: Try Gecko Linux.
