Yes.... it is a better printer in many respects. Most professionals remark the images are noticably superior in gammut, metamerism, and to a lesser extent resolution. Ink stability with the UltraChrome inks is vastly improved.
And of course, in B&W printing it blows everything else away. I have heard experienced photographers compare the 2200 prints on Red River papers as indistinguishable from wet processed prints to the naked eye.
If you want the upmost quality, the Colorbyte ImagePrint RIP for the Epson 2200 blows away the native Epson driver. At the Seybold conference there was a consensus among well regarded experts that the ImagePrint gets the most quality out of the new Epson 2200/7600/9600 printers
