Which Desktop Environment...?

I am trying to figure out which Desktop Environment to choose. I have narrowed it down to either the Xfce OpenSuse livecd or SOAD (Suse On Active Diet). I don’t want to install the main OpenSuse live cd and throw all of these different DE on there. I have tried both of the cds and have a question… which one would be more “stable” I know that e17 is not officially stable but it runs pretty well. and I know Xfce runs fast also but which one would be more likely to give me the best support.

I am running:

Omnibook 6100
512 mb RAM
