A handy-dandy index of a wide assortment of 35mm films.
Unfortunately, none of these entries is said to have a down side. Such is the only editorial decision that can be made at such a magazine.
I think I'm going to start using Fuji Provia 100F and 400F.
I wandered into that link myself a while back and I found out that I've had better luck figuring out what I liked best by using different film. Surprise surprise, I'm happiest with the cheap stuff: Regular old fuji 100-200 negs, sensia 100-200, and most b/w films with a memorable grain.
