I like and use the Foma for some stuff but there is no comparison quality wise. Tri-X is my favorite B&W film ever and just far superior to Foma. I don't shoot much B&W in 35mm anymore but when I do it's mostly Tri-X either rebranded or otherwise. I shoot both in 120 and probably 5-10 times more Tri-X than Foma. Tri-X is far, far superior by any objective measure but Foma does have its own look and can be fun.
