GNOME Shell is currently in active development and while many planned features are not yet implemented it is stable enough for everyday use.
Probably not what you want to use if you want things to just work.
Are you saying package managers cause errors? While installing? Something is badly wrong. If it happens with multiple distros with different package managers it sounds like a hardware fault.
