I actually kind of hate both.

KDE is an unopinionated Windows clone built of a shitty proprietary base. Stuff mostly works well though, I can’t deny that. It just looks and feels like crap.

GNOME development is stupid. They have a binding for every language you can imagine, but the widgets leave you up shit creek and Gnome thinks it’s smarter than you. Gnome looks pretty good, but after trying in earnest I don’t want to work with it.
