Hi Chris, I voted fiber, but you asked which has greater value. If you go to sell a print, you will usually get more for the fiber print. It also is much harder to print well on fiber than the other media listed. However in the darkroom, I print about 10 RC prints at for every FB print I make. It just makes sense, since I can make about 5 RC prints an hour, but only one (or less) fiber prints in the same time.
I scan my contact sheets and print them on the epson.
