On my side it’s running since years without problems. I would never use arch on a business workstation with debian testing I see no problems at all.

Yes it runs quite stable. But the packages and their configuration can change.

If you’re looking for something more conservative, the stable branch fits better but on a desktop it’s very old (like an Ubuntu lts)

Somewhat but it is a rolling release. Packages will be major-updated constantly.

There where Times when Ubuntu was Marks baby, but nowadays with pro, advertisement and tracking in the terminal an AppStore, everything has to have a businesscase.

I would recommend just plain Debian either with flatpak or in the testing branch. It’s almost the same, stable as a rock and driven by a community.

Maybe you should switch your favourite then?

The enshittification of Ubuntu will not stop on an enforced Appstore.
