This is only my opinion...
IT depends upon your taste. I prefer to shoot portraits that are a bit over the top when shooting in colour and very traditional when shooting B&W.
As films go I prefer the palette of 160NC over NPS, but do not like 160vc at all. For faster films I like 400nc a little better than Fuji's NPH.
I agree with dave about testing first. If you shoot 120 one roll of each may not be sufficient. I rate the portras and NPH at half their labeled speed or a little less depending upon contrast (desired or present). NPS is a bit strange, it requires a lot of exposure (~50iso) for shadows, but blocks up far faster in the highlights than the other films and the palette to me is too plastic without being exciting (like NPC or UC).
