George,
From what I can tell (and I'm just a newbie to Linux), the 'which is better - GNOME or KDE' question is much like asking 'which is better - Mercedes-Benz or BMW' in that it appears to be very much up to individual tastes.
Though, I am a *complete* newbie (I guess that would be 'incomplete' then eh?) so I might be completely off track.
Personally, I use GNOME just because it looked kinda weird. Beyond that I haven't seen a big difference.
BTW - where does the 'window manager' fit into this debate as well - I understand that different ones of those ALSO change the look and feel of the linux environment.
Regards
