Long time Novell Admin, but Linux Newbie.

I have been playing with NLD for a few months now, but I just
installed OES
Linux for the first time. I find it interesting that in NLD they use
Gnome
and in OES they use a KDE Desktop.

Mostly out of curiousity, I was wondering why??? Why default to Gnome
for
Desktops and KDE for Servers??

Is there any benefit to using KDE on a server verse Gnome?

Thanks
Bob
