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.
