I am newbie and this is my experience. Gnome runs faster and gives me
less trouble :)) KDE is more fancy and has more sofisticated
aplications in it. If you boot to any of those you have them both
available, for some reason some KDE stuff is on strike when run from
Gnome in that case I call it from command line and basta, usually
works. So I like Gnome since it doesn`t look like windows and acts
more simple and runs faster on my old hardware where I try to learn in
before I will dump it on serious machine and try to do some
geophysical modeling. So I guess you can choose what ever you like
better. I like to work in command line world since I have been arround
since the first CPU like Z80, 08086. My first machine was 2MHz fast
and was talking "Basic" :). I like when world is simple, so the Gnome
seem to me. ed.
