In the end I don't care whether the "default" Fedora is KDE or GNOME, as long as the spin of the other DE is maintained well. Except for the ootb experience which is better on the GNOME version with setup steps for proprietary drivers and whatnot, the KDE spin feels like a first-class citizen.
But KDE just makes more sense for most users I feel. Currently you start wondering where your tray icons went (for example) when switching from a non-Linux OS. For gaming, KDE is simply more mature with built-in Wayland VRR support for example.
