The Fuji Pro 160C, I find, renders everything with a vile green cast. This is true across emulsion lots and processing sessions, so I think it's intrinsic to the film. The 160S is fabulous, as are the Portra NC's, for portraiture.

But I like 2F/2F's suggestion: try them. If I were grabbing one film for portraits in good light/studio, FC 160S. In other conditions, FC 400H or Portra 400NC. They are all splendid; matter of taste. I find the Fuji films more "neutral" in their rendition, with less "personality" than either variety of Portra. They also seem better able to handle a wider range of lighting conditions, from early morning/late day "warm" light to harsher overhead bright stuff to overcast diffuse gray conditions.
