I'm hesitant to comment further seeing I've attracted the ire of some people with my comment, but anyway. I too used Arch out of curiosity about like ten years ago, during the first "Arch, BTW" memes, and found it too unstable, but that's expected from a rolling release: update too soon or too late, and something could break. I didn't mind, as it was a hobby.
Eventually, I got more busy and had less time to tinker, so I migrated to Ubuntu LTS, which has some small warts, but has needed practically null babysitting compared to Arch. I was surprised when the Arch memes resurfaced this year, but that's the only growth I've seen. None of my Linux-savvy peers use Arch, BTW.
FWIW, the only breakage I've seen over the past 5 years is amdgpu bugging out on latest kernel releases, which is easily solved by running linux-lts.
I've had way more problems with Ubuntu trying to be convenient and bringing in lots of Windows-style automation that breaks more often than it works (and when that happens, you're really on your own since you have no idea how it's put together — just like in Windows).
Or even just bugs that were solved upstream ages ago (and have been available in every rolling-release distribution, including Debian testing/sid).
The current Arch installer suggests btrfs with snapper, so you get automatic snapshots pretty much out of the box (need to check one flag in installer), and can easily rollback if something breaks. Not something I needed, but it's there.
