Xfce, on the other hand, is a more traditional desktop environment. It's also lighter and faster than other desktops, so it's fantastic if you have an older or slower computer.
I also like the way Xfce looks compared to Unity. Yes, some might consider this a shallow reason to choose a desktop in Linux, but I think it's quite valid. After all, when you pick a desktop you might as well like it since you'll be using it regularly.
What's your take on Ubuntu versus Xubuntu? Which one would you pick?
