Xfce is fast, it doesn't crash, has fewer graphics issues. It works great at an 433MHz machine at home, where Gnome barely doesn't work because of all the issues (Menu's Blacked-out).

It loads at the half speed of KDE, and a little bit faster than Gnome.

Easy to customize, alot to customize.
Loginscreen looks great, clean look.

And doesn't crash, and actually responds most of the time (*cough* Gnome, Windows *cough*)

So my point is...
ALL HAIL THE XFCE MOUSE :D
