Please note: These problems don't crop up in non-rolling distros nearly as much. The transitions are held off, managed and only rolled out for new major versions of a distro.
There are benefits to running Arch, but 'just works without breaking' is not something it's good at.
Indeed. I love Arch and generally it has been very reliable for me (more so than Kubuntu or Suse ever was previously). However, the transition to systemd was one of the few times where I had a issues. Systemd is pretty mature these days, but back then it was much buggier and less well-supported.
In the long run though, I'm glad to have made the switch. I find it much easier to maintain. I also use FreeBSD at home and while I love it too, some aspects of maintaining it don't feel as nice (I suck at writing init scripts apparently).
That's kinda true, but I did use non-rolling-release distros, particularly ubuntu for a while, and they're generally more buggy (and I expect Fedora is even buggier than that).
