I use mostly Ilford FP4 but also use the Bergger 200 and the forte 200. None are the same. Forte I have had a great range of contrast across the rolls I have shot. In the 4x5 it seems comperable. I use mostly PMK for developing, and with some of my 4x5 use HC110. Personally if the price of the Forte was similar to the Ilford I would use it exclusively. They now have a 100 version as well. I have shot a few rolls of efke, but for the current cost of it, I will stick with Forte or Ilford.
