Obviously I'm not Chris, but I have compared my Spandex screen directly to a sample of Centerstage XD and can probably answer your question.
Other than being noticably brighter one other benefit of the XD material that quite surprised me was how much sharper image detail appeared to be.
I have tried spandex in every configuration possible (Silver over white, white over silver, white over white) and in every situation the spandex gives a slight halo effect around each pixel. Essentially when hit by a beam of light, the spandex "glows" in a larger area than that hit directly. The XD in comparison maintains greater localized contrast.
In my particular situation a little fuzziness around the edges is a good thing because I have a viewing angle greater than 50 degrees with a 720p projector. The spandex makes visible pixel structure bearable. Also I sit quite close to the screen (about 9 feet) which may allow the XD weave to be seen at times.
In my mind the Centerstage material is well worth the price difference if it works in your particular install.
Spandex is cheap and XD samples are free. I encourage you to try for yourself.
