Canson Rag Photographique 310, is in my opinion, the best smooth rag paper available. Smoother than all the Hahnemühle rag papers.
For a soft texture, BFK Rives, if you can afford it. Somewhat similar to Epson Velvet Fine Art, but in a heavier weight.
For medium textured paper that really holds resolution, Hahnemühle German Etching. Some OBA content, but quite low.
For heavier textured papers, it is really up in the air.
Epson Hot and Cold pressed papers are really very good for their price, but my quarm with them is that the bright papers are a mite too bright, and the ‘natural’ papers are a little too warm.
