I really don't see why Gnome2 lovers and Gnome3 haters fall back to XFCE and LXDE automatically, without even trying the KDE spin... Is there some silent collective KDE-boycotting in place here or what?
Xfce is basically what Gnome 2 should have been, but perhaps with a few rougher edges. KDE is a very different experience. Going Gnome 2 to XFCE feels like switching between different releases of a desktop rather than a complete desktop changeover.
There are lots of desktops to try - E for example shouldn't be overlooked either.
I still remember KDE3->4 and I'm afraid after that I don't trust there won't be a similarly catastrophic KDE4-5 8(
