Personally – Ilford Gold Fibre silk, knocks my socks off. I have pearl as well and it's quite nice but I like the surface texture of the silk which is more like something out of a very nice photo book.
I second the Ilford Smooth Pearl.Just make sure that you get the one for pigment based inks,also make sure you go to their website and download there ICC for your printer.I used this paper with there ICC and could not tell a difference at all in color from the Epson paper
