I am excited about all the changes coming to our DEs!
I like to watch videos published by Nick from The Linux Experiment. In the latest video he talks about the developments in the new Cosmic, The quality of life touches and polishing of KDE, and the apps coming to gnome (like snoop). It is all really cool and I can't wait to try them all :)
To be honest, one of the reasons I switched from KDE (after 15+ years of using it) was the better X support on xfce. I use an nvidia card, so before I switch to wayland support for nvidia drivers has to be much much better.
