Atomic distro sounds like an interesting way to avoid breakage due to admin/user mistakes, so it’s a good suggestion. But it doesn’t help much with bugs in new software releases.
So the best choice depends on what exactly caused instability in OP’s case.
Recall the time when Windows came on a DVD, had no Microsoft account option on install, no ads in settings nor in the startup menu, no AI slop.
It was still shit, but it feels shittier now, and harder to setup and configure in a way that’s bearable.
