In my experience, joe, the ultra is by far the best film of the bunch. The delightful side of irony is that it's also the cheapest. I had some real QC issues with Forte, but everything I've used from Foma has been just right.
Right now, to me, the best cheap conventional black & white film is Fomapan 100 aka Arista.Edu Ultra 100 or the 400 equivalent. Excellent film for pennies. Can't beat that with a stick... 😱
