I bought both. I shot both. They are both good. But, when enlarged, the HP5 has a different paisley shape grain than the very point shaped grain of the TRI-X. If you look really close. I prefer the point shape grain. There are probably cases where HP5 tonality is nicer. But there is no test that will say one is "better" than the other. Pepsi tried to do that with Coke. Prove their product "tasted" better. Coke is still doing fine. Different tastes, different soda pop, different film, it is almost a silly question except if there was something wrong with one of the films. Like the film speed is way off, like APX400, or the film is blue and curly like the old J&C films. But that is not the case with HP5 and TRI-X - If HP5 was cheaper here than TRI-X (it is not) I might get used to the paisley shaped grain ....
