My two standard "gloss" papers are the Ilford GFS and Museo Silver Rag. Last weekend I got samples of the Canson Photographique and the Hahnemuhle Photo Rag Baryta and tested them out. All four papers are excellent and give slightly different results with regard to finish, color gamut, paper brightness. As noted by Rob, both Rag papers are thicker and stiffer. They won't buckle as much in your printer. I've not had any problems with any of the papers regarding scratches during printing. The price differential when I looked is: Canson < Ilford < Hahnemuhle < Museo.
