I use KDE Neon. I was and still am a big fan of arch, and while I appreciate the philosophy behind it, I just didn't feel like setting it all up this time around, KDE Neon had the software I was looking for and just got out of my way (outside of needing to deal with NVidia drivers, which seems like a pain wherever I go, I eternally hope for improvements from Nvidia)
I use KDE Neon as well, but I dislike every minute of it. The Discover app just constantly breaks when trying to update packages from several sources. Having to juggle apt and pkcon is a chore. Sleep just never seems to work right etc.. When I have an extended weekend, I'll start distro hopping again. Either back to Arch or trying out NixOS.
