If you are a KDE user or are interested in it, I've been running KDE Neon for a few months and don't plan on changing any time soon. Stable release, Ubuntu LTS based without the forced snaps (though snaps are in the repos if you want them), comes with the standard Ubuntu LTS repos and flatpak installed out of the box, with the one difference there being that it will update to the latest stable version of KDE software as it's released. Basically a de-snapped Kubuntu LTS with all the latest KDE stuff. Works great for me.
