I'm kind of a fan of Kodak UltraMax 400 and 800. Every so often they change the manes, but basically it's the same 100, 200, 400, and 800 under various names like "Gold," Max" or UltraMax." I expect a new name in a bit.
The HD 400 I thought was not much different than the Max 400, but I bet it's going for less grain, not that grain is an issue in the other 400.
I don't have any scans to show right here, but compared to say Fuji Superia, reds are red, not pink. Superia always seems to have a green cast to it to my eye, but the Kodak 100, 200, and 400 always seemed to catch the brilliance in a scene rather than muting the colors.
I'd think it depends on what you prefer for "look." I like them both, but I shoot the Kodak films myself.
I found the Portra films to be "wrong" for outdoor photography. They work, but nothing looks right. I'm pretty sure the reason is the Portra line is designed for studio use with controlled lighting, not an overcast day with pockets of sunshine. The NC was like Superia but without the charm, if that makes sense. And the VC was just odd, not dull but not hypervivid or anything either. I prefer Gold 100 or the UltraMax 400.
And again, it's personal taste. I judge films by the pictures *I* take with them. I really like what other people do with films I don't like to use.
Kodak and Fuji seem to have a consumer line and pro line of films. I don't know about Fuji, but Kodak's consumer line seem to be better for outdoor and candid shooting than the pro line, which seems to me to be geared towards controlled lighting.
