Honestly for me it’s very subjective. With GNOME, I need to install and configure a lot of extensions to get it to work the way I like. I was surprised how many of these small tweaks and features are already part of KDE. Out of the box it’s a lot closer to what I want and the rest of the small customizations I want are just right there in KDE as options.

With GNOME extensions I always have to wonder “which crappy extension broke now, and what is the new one everyone is moving to/how to fix it”.

Just generally a lot less headache for me. I also could swear it’s more performant and generally feels snappier, but it’s so hard to tell on modern fast hardware anyway.

Nvidia drivers?

I was always a GNOME guy. Not sure why really, maybe it was the state of KDE3 vs GNOME2. Never really looked at KDE again and assumed there is a reason all the popular distros pick GNOME. then 3 years ago I tried KED, and was blown away. Now I’ve completely flipped my position on it.
