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.

Somewhat obvious tips to get a more stable experience:

• Use a distribution that favour stability over being on the bleeding edge. Like Debian stable, or another distribution that maintain LTS releases,
• Install software from the distribution’s official package repositories. Avoid third party packages and repos as much as possible. If you really need a third party repo, verify it’s compatible with your specific distro and has reputation for being well maintained,
• When you do see a problem, take time to troubleshoot and if necessary make a bug report with necessary information for developers to identify the problem, so there’s a better chance to see it fixed.
• If you use Linux in a professional settings, there is paid support available out there, in some cases this get you priority for bug fixes.
