There is always a discussion about which paper is best for printing fine art photographs. Some folks prefer cotton rag, others prefer archival papers by the major players like Hahnemühle, Fuji, or Moab to name a few. To make it more confusing, within each brand are papers with different properties and surfaces. Something you may not know, it is actually the ink, and I use pigment-based ink, that has the archival property. The paper is the carrier for the ink, and depending on the paper's structure, each absorbs ink differently. A glossy surface can enhance detail, a heavy rag can mute detail, and a pearl surface somewhere in between. I'll tell you why it really doesn't matter, because if you are buying one of my photographs, whether it is a limited or open edition piece, I have already picked the right surface.
You don't need to know the difference between Hahnemühle Photo Rag and Moab Slickrock. You need to know the print in front of you was matched to that image, on purpose, by me, the artist who made it.
