Just to offset the predictable groupthink in this thread: Ubuntu is fine. In my experience it is rock solid and has been for years. Doubly true for the LTS versions. Yes there there is the slightly troublesome issue of Snaps and the even smaller one of self-advertising. But IME the installer is very solid and that is a crucially important issue for prospective normie users. Ubuntu is still a flagship distro and IMO it now deserves more love than it is getting.
