Both are top quality films that can make nice images. Tmax requires more care in developing; smaller changes produce stronger results. Needs more fixing and washing as well compared to traditional films. The upside is that it is so versatile. Someone familiar with it could emulate any look except for the grain. I've used tmy/tmy2 since it came out and have this familiarity with it. John Sexton would be a more reputable person of skill who can make the film do what he wants. It'd be a foolish business decision, but I think Kodak could discontinue tri-x and we'd be able to adapt to tmy2 because of it's versatility. But people who like grain and sloppy darkroom workers would howl.
