KDE no doubt. GNOME is a minimalist that depends on extensions to provide basic functionality, while also being a giant fatass. KDE works from the install, provides a sensible workflow, and has better tools.
But I’d only use KDE on a rolling release or a 6 month release schedule distro. Their approach to development really doesn’t suit stable ones.
I just feel like they wanted to do arch, but
pacman -Syu
was too awkward
