GNOME. You have to install an extension to get a dock at all. Almost nobody runs vanilla GNOME because it's missing basic things. They refuse to have a system tray. I don't particularly like the system tray, but that doesn't change the fact that some apps continue to run the background when you quit them by closing the window. Up until recently, you had to install a system tray extension so you could properly quit programs like Steam. Finally, the GNOME developers added functionality where you can see background apps and close them, but it's hidden behind a few clicks. A clipboard manager is another one. KDE includes it by default. GNOME? There's an extension for that. And the problem with extensions is they always break every single time GNOME is updated.
