In the film world i've only shot Portra 160 and Tri-X 400. I love the way the Tri-x looks.

I have seen shots at higher speeds and it makes me glad I shoot digital.

Part of the character of Nikon's noise in some of their cameras is it seems to be more film grain-like as they removed the chroma noise. I find this is a nice texture with my D200 and D2HS (when the d2hs shows noise that is). In fact, I shoot the D200 in black and white mode sometimes at high ISO (usually really high actually) to simulate the look of the tri-X for effect or fun.
