Explanation/comparison of differences between ubuntu/kubuntu/xubuntu

Registered by Kẏra

Although Ubuntu, Kubunutu, and Xubuntu all say what they are on their respective websites, there is no official explanation of the differences and comparison with screenshots, etc. I just helped out another user who was confused about the difference and i remember being confused myself when i first tried out Ubuntu. Having a page like this could help out new users very much. The closest page we have to this is here http://www.ubuntu.com/products/whatisubuntu/derivatives but it really doesn't offer any good explanation or comparison.
