I run Arch for 10+ years, currently on both of my computers that are fairly different and the maintenance for me is minimal if any. The opinion thay aRcH iS uNStaBLe comes from people who can’t read Wiki carefully enough to set it up properly. Updates that broke something on its own and not as a result of users’ mistake are really a rare thing. I heard of something like that maybe twice during the years and even then it didn’t affect me.
