I think compatibility is an important consideration. This is why I bought a laptop preinstalled with Ubuntu.
Then you want "compatibility out-of-the box", because anything that is compatible with Ubuntu can be made compatible with any distro, specially with the one with an Arch community
lol, that may be true, but not everyone want to compile the driver for a sound card from the source. For desktop users, usability is a big concern. Out of the box experience is important, and hardware comparability is a big one. Ubuntu worked out of the box on all my computers so naturally I am a ubuntu fan now.
My mistake its from git but lightdm is from launchpad https://www.archlinux.org/packages/extra/x86_64/lightdm/
TBH! Arch has been way less buggier than Fedora for me, only the latest Fedora has shown some promise. Also yes, Fedora does testing like the Ubuntu six month release.
