I use a 4x5 (folder) and 503CW. I prefer my 4x5 mainly because of the movements, but also because of the workflow, the pleasure of composing on the ground glass, and, arguably, the results I get. However, when I cannot travel with it, Hassy is a wonderful replacement, compact and light. Still, I've never used my Hasselblad for a landscape not thinking that I wish I had the 4x5 with me at the time. For portraits it makes less of a difference.
