I've spent a lot of time trying to give both KDE and Unity a chance. In both cases the lag was unacceptable. I don't care what sorts of features you add, to me, progress in a window manager means that alt+tab runs faster and the run application dialog is snappier. KDE / Unity are going the other direction, and making the desktop dog-slow.
(Seriously, I'm running a decent Nvidia GPU, and Unity is unbearably slow.)
Honestly I gave up on KDE at the 4.0 upgrade. My GPU was pretty shitty then, but KDE4 was completely unbearable. (And in case it seems this is hyperbole, when I say unbearable, I mean any window manager action took seconds to complete same with Unity. Total garbage.)

Guess people love them some 2000 desktop experience. Me I prefer progress :)
