Depends on the person. Someone who just wants a stable desktop that works? No. Someone who wants to learn how Linux works, and likes to tinker? Yes.

The only thing I don’t like about stable distros is being 3-4 versions behind on software. Back when I was using Ubuntu I used to get frustrated because I wanted to use the latest version of things like LibreOffice, but couldn’t without bypassing the repos, which can cause issues down the road.

Once it’s installed Arch is just as easy to use as any other distro. It’s “unstable” because it’s rolling release, sometimes issues crop up with bleeding-edge updates, just keep an eye on the forums before updating.

I’ve only had to deal with a broken system a couple of times, both were 100% my fault, and both were fixable without reinstalling. Even when something breaks it’s pretty forgiving, as long as one is paying attention and not afraid of reading documentation.

I dunno, I used ubuntu (or some flavor of it) for 15 years before Arch. I will say that the first time I installed Arch, I did it solely to prove to myself that I could. After that, I fell in love with it as a daily driver for a lot of reasons. The AUR is a big one, and the fact that it’s so well documented also helps. But really, once it’s installed, Arch isn’t any more complicated than any other distro to keep running.

I did switch to EndeavourOS, though, because once one has installed Arch the “Arch way” a few times I don’t reallly see any benefit in doing it again.

Arch’s package manager, pacman, manages dependencies for you and is quite robust. Arch is much simpler to run and maintain than Slackware, I think.
