please dont mention Gnome and KDE in the same breath
KDE 4.10 and above has only ever crashed on me once it took less than a second to recover with a little window bug message, i clicked it off and the thing that had crashed was working again.
KDE isnt an instant like for many i do think you need to customize it to get it exactly as you like but over time your desktop becomes ridiculously specific to you. An example is the large amount of windows settings functions where by you can have certain applications always start on a particular workspace and in a certain part of that screen which means when you auto load them on login your desktop is always as you like with the applications always launching where you know there going to be. Useful for business workflow imo as you can dedicate 4 tiled program windows like share price indexes / stock charts or perhaps chat windows to be set on a named workspace as is and simply tab between to keep and eye on them then tab back to the gaming desktop.
