Never having uses PSP it is hard to me to judge, but I can't imagine not having the tools of Photoshop at my fingertips. Even the older versions are awsome, though CS is truly an comprehensive program and the one to own. It may not be as easy to use, but it is the most powerful. If PSP meets your needs as a hobbyist, then I say stick with it. As a professional, I feel I need Photoshop and all that it offers.
