It's TX for me - not even a close call. I've been using it for more than 30 years because both its characteristic curve, with a long, gentle shoulder, and its forgiving handling both in the field and in the darkroom - not unrelated to the curve - are exactly what I want.
I should say, I'm not after the grainy/contrasty thing that some people cite as a reason for using TX. I'm not looking for grit and "punch" (though if a picture happens to come out that way, so be it). Quite the contrary - with generous exposure, conservative development, and printing at relatively low contrast, TX delivers a lovely, long, quiet, subtle, tonal scale, with information all the way from deepest shadows into the highlights. If I must make a tradeoff, I'll gladly accept reduced tonal separation in the highlights in return for full information in the shadows.
I don't care about the grain. It's lovely, not particularly pronounced when the film isn't overdeveloped, and is just part of the rendering. When I want grainless I use large format and contact print.
The flip side of this is that for my taste, the long straight-line response, reduced blue sensitivity and increased sensitivity to development changes of TMY compared to TX are bugs, not features.
