I have heard great things about Efke. Only ever shot one roll. It was ok for me, it does curl badly though, atleast in my experience.
Me and Fomapan had a bad experience. I bought a pack of 4x5 film that was just a bit too big for standard 4x5 film holders. Then shot some in 120 that had bad production marks on it. Forte was better than Fomapan in my opinion.
To me though, you can't beat the emulsions made by Kodak, Fuji, and Ilford. If you want to save a few cents per roll of film to me it's not worth it. Stick with the big names. They have the highest quality standards, and are the most consistent from batch to batch.
