I've only recently began color work, and my second stab at it was with Fuji Crystal Archive type II with excellent results. I use the ARISTA 2 LITER RA-4 chemistry from Freestyle. I analyze the first print with a color print viewing kit and by the third print, usually, I have acceptable color.
I have not tried the paper with Portra - so thank you for the warning! I shoot mostly Fuji Reala and Superia 400, with Kodak Gold 100 & 200 being my other favorites. The paper certainly seems to work well with the Fuji films.
