I've only shot a couple of rolls of the SS and then I went back to Acros. I prefer the grain of the Acros film to the SS, but I also didn't try pushing or pulling it. IMO, the difference in grain is very subtle until you start printing larger than 8x10. I also found the SS to have a little more contrast than the Acros. My preference is to control contrast via filters (both with the camera and enlarger) instead of with the film.
I've actually shifted away from the fujifilms after they discontinued their Neopan 400, which is my favorite film at that speed.
