Desktop Managers: Compiz vs Vista Inspirat, which is better?

To be fair, I used the same background for both desktops with almost the same features.

Windows XP Vista Inspirat with Cube









Windows XP Vista Inspirat Desktop









Ubuntu 8.04 with Compiz









Compiz with Desktop Cube.










Compiz Cube Glide










So, which do you think is better off as an Eye Candy?

Please note, compiz isn't compatible with Windows as it is only available for Linux.
