Ubuntu has its ups and downs when you’re actually living with it, but they have a fantastic installer experience. I have had my fair share of bizarre dead ends with other distro installers, like Bazzite telling me “you need -860GB more space”. Ubuntu puts you in a solid live-iso OS where the installer is just an app that you can drag to one side and run other tools before continuing. It tends to do sensible things if I go off the beaten path with a more advanced install.
Nowadays, I am happy with debootstrapping or btrfs send’ing an existing Debian install to set up a new system for myself. I still think that Ubuntu is reasonably likely to be a good experience for a newcomer.
