To give another opinion, I also thought GNOME 3 was not good, until around a few years ago. It's a lot better since then, they really ironed out a lot of the issues so you see the contributions start to raise up again recently. The extension API is also getting a lot more stable, but it's not totally there yet. One area where I think KDE does a lot better is with QML. At the moment GTK doesn't have anything as nice as that to build apps, and that hurts contributions. There's some neat new declarative UI things like vgtk [0] that are looking promising though.
