I liked the surface of my Graphire4 better than the Intuous4. The Intuous takes greater pen pressure (no, I'm serious) to make a thick line, and the natural, paper-like feel on the surface that they market as a good thing was never a plus-point for me. I like the feeling of smooth plastic better, and the textured surface wears down the nibs. :/
XD But needless to say, I'm used to my Intuous4 now, and I like it. Like Mac vs PC, it's all a matter of preference.
