Over the past 50 years I've used many different films, while in college I shot a lot of GAF, why? Our photography instructor hated Kodak the Big Yellow Father in Rochester New York. He didn't hate Kodak products, just the company, all of our darkroom chemistry was GAF, we used GAF and Dupont paper, and GAF film, the only Kodak film I used was TriX, GAF 500 was crap. After College while in the Air Force I used what ever the Air Force was using, 80% Kodak, some GAF and some God knows who coated it. While working for the wires I used Kodak and Ilford, my preference being Kodak, PlusX and TriX, for personal shooting in MF I like Verichrome Pan. After I return to Arizona I used Kodak for many years, then decided to buy a less expensive film for "walking around" and Tmax 100 and 400 for any paid work or travel. I used Foma, 200 and 400, then Ultrafine, Ultrafine xtreme, and now back to Foma as my walk around film. I buy an odd roll of Ilford Pan F, sometime Kodak double X, and just ordered a roll of CATLAB 80, what I call "just the hell of it."
I find Foma 200 and Ultrafine to be a pretty good films, good tones, decent grain and resolution.
