Can you please explain why it seems obviously superior to GNOME? I'm in the market for a new DE after using i3 for a while and would be interested in your reasoning.
KDE is an extremely integrated and batteries included DE. File manager can manage SVN/Git/Mercurial repositories and connect to anything. Akonadi can handle your mail and calendars at the background. Included apps (Gwenview and Okular) are very powerful.
Desktop effects are not gimmicky but useful (e.g: dim inactive windows). Power management makes sense and is reliable.
KDE can behave like anything you like and doesn't bury power-user related features somewhere. It's all visible. Multi-speaker & multi sound card management is also better, more obvious.
