I bought several sample packs for art prints and trading cards. Red River papers are comparable to Moab and Hahnemuhle papers with some slight differences in color and texture; it all comes down to preference. However, Red River paper is less costly and provides ICC Profiles for my printer, the Epson Eco Tank 8500. Moab, Hahnemuhle, and even Epson (some papers, but not all) do not carry ICC profiles for the Eco Tank.
Overall, papers retain color well and prints are sharp. Favorite papers include 60lb. Polar Matte and Aurora Art (comparable to Moab's Entrada Rag).
