> can be more stable than relying on a distro's fixed release cycles

Stability for a distro means “doesn’t change” not “doesn’t crash”.

Debian/ubuntu are stable because they freeze versions so you can even create scripts to work around bugs and stuff and be sure that it will keep working throughout that entire release.

Arch Linux is not stable because you get updates every day or whatever. Maybe you had some script or patch to work around a bug and tomorrow it won’t work anymore.

This does not say _anything_ about crashing or bugs, except that if you find a bug/crash on a stable system then it is likely you can rely on this behaviour.

Agree. If you use a rolling release you definitely need a strategy for stability. I turn off automatic updates and schedule planned full updates that I can easily roll back from. I've had two breakages over the years that required snapper rollback. (Rolling back from a major distro upgrade isn't that easy)

It's a tradeoff that I'm happy with. I get to have a very up to date system.
