Course set: the first alpha of Pop_OS 24.04 is scheduled for release on August 8th. So if you've been counting the days until you can try the new COSMIC
I use Pop!_OS on 2 machines daily with KDE Plasma and am happy with it. I use KDE Plasma because COSMIC is too GNOME-y for me. The only thing I liked better in COSMIC was the fractional scaling- that was way better than the options I have in KDE.
