In OpenSUSE there is a good option for a good XFCE, also. It can be installed
quite easily (but slowly).

I hate openSUSE's KDE4
Sadly, the OpenSUSE repositories are poorer than those of Ubuntu.

By the way, for using XFCE in Ubuntu I do not recommend any more to

sudo aptitude install xubuntu-desktop

Rather than this, install an original, serious XFCE

sudo aptitude install xfce4
