Gnome or KDE?

After a lengthy debate and debacle with KDE I have reverted my system configuration to GNOME which seems to be practically good and productive for my purpose. KDE is all the more good but power-packed with services and utilities which I do not get to use at the moment.

And I also want to share one thing. One of my friend who is new to Linux but got inspired by the simplicity and elegance of it always gets confuses between Ubuntu and Kubuntu. I would like to clarify. Ubuntu and Kubuntu are two flavors of Debian Linuxes. GNome and KDE are the desktop environments. Trust this makes things clearer and cleaner.
