I use Print File, I like them because they are easy to work with. I currently use them for 4x5, and 120. For 35 I ran out of print file pages and bought something else, maybe vue-all. I hate them because they fit the film too closely and it's difficult to get it in and out, compared to my Print File Pages.
Most of my contacts are done through the pages, specifically because of the less handling aspect. Doing that impacts sharpness a bit, and if you do the minium time to max black thing, you have to compensate, as the page adds a slight bit of density.
I have negatives that have been in Print File pages for 20+ years, both the pages and the negatives are fine.
