Yes, Tri-X is a wonderful film. So is TMY-2. But OP doesn't want to use Kodak. End of story. He's left with HP5+, Delta 400 and Fuji. Delta is a tabular grained film which will look different than HP5+. So maybe a good try would be HP5+ and Delta 400. Start with those two. They are both superb films as Ian Grant noted above. If Rodinal is your developer, use Rodinal.
I think this quote about covers it. There are a few other alternatives (all I can think of are the ones mentioned by the OP: Kentmere, Foma, Rollei), but the Ilford offerings seem like the natural place to start. I kind of like Fomapan 400, but it seems like Rodinal would emphasize all its weakest characteristics, especially in 35mm.

To my eye, HP5+ and TX are more similar than different in normal usage. I mean, obviously there *are* differences---they behave very differently in Diafine, for instance---but at box speed, normal lighting and contrast, no special effects, those differences aren't that big (certainly as compared to T-grain vs. conventional-grain films, e.g.). I don't think TX is automatically a reason to reconsider the OP's desire not to use Kodak.
