From ratpoison to Unity, I must have tried just about every Linux desktop environment available. The best Linux desktop, in my view: my main computer continues to run KDE's Plasma. No other alternative can match its design philosophy, configurability, or its innovations on the classical desktop.

At a time when the Linux desktop offers six main alternatives (Cinnamon, GNOME, KDE Plasma, LXDE, Mate, Unity and Xfce), KDE Plasma consistently tops reader polls with an average of 35-40 percent. In such a diverse market, these figures indicate a broad appeal that other Linux desktop alternatives can't match.
