My experience with KDE has been great, until you start using proprietary drivers / hardware. I got an ASUS ROG Zephyrus G15 (solid laptop aside from the spotty keyboard) and it was an absolute nightmare getting the keyboard lighting and the laptop GPU to work reliably with KDE Neon.

I ended up just nuking it and restarting with Gnome. Gnome turned out to be a lot more restrictive, but the initial setup load was significantly less than KDE. The graphics card / keyboard LEDs just worked straight out of the box.

The new widgets in KDE were pretty cool and very fluid. The desktop state didn't save for me though and any time I rebooted/logged out, everything disappeared from my desktop...
