Debian Unstable. Because I know my way around Debian more than any other distro, but I need the newest Gnome for proper support of tablet mode on my convertible and that’s something you can’t install via flatpak or backports.

Downside is that it pushes package updates that weren’t tested for compatibility with each other, so you need to know if what apt suggests makes sense before you hit “Y”.

I’ve tried Arch and OpenSUSE Tumbleweed in the past, but both rely too much on packages built by users without proper integration with the main repo.
