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.
I'm on AMD and have 3 monitors with 3 different resolutions and 3 different refresh rates, so X11 just doesn't work for me
That's a good reason indeed. I have three monitors myself but all the same refresh rate so it's all good on that end.
