I used to use it on my laptop and found it to be stable and solid. I never encountered any of the theoretical issues people brandish about. The GUI app store was really good (pamac) and frankly if it was included with EndeavourOS it would be perfect and I could recommend EOS to anyone; without the GUI app store EOS really are intentionally limiting how popular they could be. The default wallpapers were a little bland.
I switched to endeavour as when wanting to move away from Ubuntu on my desktop Manjaro didn't like my multi monitor setup (and nor did anything else I tried other than EndeavourOS and Ubuntu). If that had worked I might still be using it now.
