About a month ago I tried ~10 different Baryta's and went about blind comparing the look, feel, texture, etc. All of this on a 3880. I'm no expert, so take it FWIW, but I felt the Canson Baryta Photographique was the best of the bunch - nice gloss, but not too much. A good weight. Color and DMAX were good.
I know GFS is well liked, but I found the Ilford paper had too much yellow. Color landscapes with greens & yellows overly skewed towards yellow. I like the Ilford GFS for B&W prints, but not so much for color. The Canson seemed more neutral in that regard.
My only gripe was the Epson 3880 and its @#$%^&*() pizza wheel marks which it does on any RC paper. If the light hits the paper right, the marks are as clear runway landing lights. Hopefully the wheel marks will be solved with a new printer later this fall.
