When I moved from SuSE 9's KDE desktop to the Ubuntu desktop, it was such a shock; KDE is all shiny bubbly transparent textured stippled zillions of buttons, whereas GNOME just takes the one you were going to click anyway and throws the rest away.
This "stay out of my face" philosophy works well for me.
I'm still working out why the KDE developers think that it's more important to be able to change the contrast of one's 3D widgets than it is to provide a large icons and high-contrast theme for users with visual impairment.
Shrug, I expect.
