From my experience as someone who uses Ultramarine Linux currently: The download page is fine, but not great as a new user. That alone kind of pushed me away, since I wasn’t sure if I was downloading the right ISO. I can definitely tell the packages are outdated. I like GNOME desktop (which is what I downloaded), but I definitely know that other distros make customizations to GNOME that I had begun to take for granted (e.g. pre-installed taskbar via GNOME extensions). I could definitely use Debian but I find it just… a bit behind? Like it definitely works, but other distros are slightly more user friendly. Debian can be customized to match those other distros, especially with Flatpak, but any distro that isn’t user friendly out of the box I don’t want to recommend.
