My Ubuntu broke literally every time I did a version upgrade. It's probably better now, but I'm not going back.
The last system that straight up broke for me was a default installation of Debian Stable, and that wasn't long ago.
I understand Arch isn't easy to use or maintain.
But in my opinion, if you use something wrong and it breaks, that doesn't mean it's unstable. And if you update Arch by simply hitting "pacman -Syu" every day, you're doing it wrong.
