Lubuntu and Ubuntu.
Other *buntu flavor
Lubuntu as well.

Kubuntu first, followed closely by Xubuntu. Unity is a distant third: my wife is using it at 12.04 now, but she's soon going to be replacing it with Kubuntu 12.10.
We installed Xubuntu 12.10 on her Dad's computer, which is a lot simpler and easier to use than Windows 7.
Unity has a lot of potential, but it still seems pretty fragile under hard use. KDE takes everything I can throw at it, and Xfce is simply elegant in its simplicity.
On my Dell XPS 15 laptop, Ubuntu when plugged in on a/c, Lubuntu when on battery.
On Dell desktop, Xubuntu because my wife prefers that over other flavors.
I'm a huge Xubuntu fan. I just add AWN for additional eyecandy, and put GNOME Shell on there for when I feel like a change - up...
... And I have zero complaints!
Horses for courses, but to extend the life of an old xp desktop, it has to be Xubuntu. Its a much easier transition from xp to Xubuntu than either Ubuntu or any of the newer windows variants. Faster than either xp or Ubuntu & certainly prettier than xp, it came out top in the most important test of all, the wife liked it straight off.
Ubuntu, I am delighted with Unity.
