I'm currently running tumbleweed on my main, mostly because that's what I happened to install last time I rebuilt my desktop.

I've been running other distros before, and I must say that (bar a couple bad experiences) I could still be using any of them.

Tumbleweed is the first rolling distro I've used for a prolonged time (3 or 4 years now?): before I only did two short experiments with void linux (loved it, but I'd rather have systemd) and manjaro (I was still young and stupid).

I don't think I'll go back to non-rolling: tumbleweed never broke on me (and if it did, it has snapshots) and being rolling there is zero update stress (has the new version come out? what's new? should I update now or wait for for the .1?).

Next time I install I will probably try nixos (which isn't really rolling - but it's not non-rolling either), which I've been using on servers for a while now and fell in love with (love-hate, that is: the learning curve is steep, the documentation poor, and there are infuriating points - but I feel like it's still more than worth it).

As you will have noticed I'm not even considering "immutable" distros: honestly, I don't see the point there (they seem like a lot of effort to solve problems I don't have).
