Most serious photographers, and by this I mean those that are actually interested in taking pictures, shoot maybe two films consistantly. To make any comparison valid you really need the same person, using the same chemistry, and the same conditions posting a variety of images and statistics for many films. The chances of this happening is very slim. Most people are not interested in expending the large effort that is required to correctly produce what you want. Still there are a few people that seem to do nothing but test films. I don't know whether I would classify them as capable photographers.
