Earlier quoted context omitted.
I mean, it is a key advantage, on ArchLinux. If you don't have a rolling release, it's pure pain: you're often just stuck with old versions of software which aren't any more stable than the current stable release.
It's only pure pain if you want bleeding edge AND stability. Non-rolling releases are just fine if you only need new features once a year.
Also, for the most part, the "Arch is unstable" thing hasn't been true for a long time. I find that it's far more stable than Debian or Ubuntu LTS on my machine because of newer kernels containing newer hardware drivers.
