I always find the product placement of Portra films to be unfortunate: I used to dismiss them as "sleeper" films, useful only for kitschy wedding portraits, according to their advertisement.
When I started comparing neg films, I was actually floored by how great the Portra looked. The Fuji line always bothers me with their rendition of greens--it's too turquoise for me. The Portra films, both NC and VC looked "truer" and are very sharp, saturated films that print beautifully on RA4 (and they scan amazingly since they got updated). 11x14 out of 400 ISO 35mm film, no grain, beautiful tones, that's impressive!
The contrast of the Portra films is not too high, so it's a plus for outdoors. NC (normal saturation) is best for straight portaiture, VC (higher saturation) is for scenes, landscapes, still lives, etc.
