Think TMax100 looks different from Tri-X. Negs to print from it are often thinner than the older films and some judge the negative rather than the final print.
TMx 100 used to(still does?) has a UV blocking layer that makes it generally unsuitable for alt processes that rely on UV exposure.
Take any film or film/developer combination you want and some won't like it for whatever reason while others will find it works well for them.
