i'll talk about films exposed at ei3200.

i think that it depends on your likes and dislikes.
imvho, tmx+tmax dev isn't that nice. for my subjects --i often shoot
jazz concerts and other very "moody" subjects--, delta3200 + rodinal
gives me better results. grain is a little bit thinner, but far
smoother than tmz. i mean: even if the grain size isn't very
different, the shape of the grain is, and i really disliked kodak.

the other thing is that tmz + tmax dev were more contrasty than
delta3200 + rodinal --1+50, as from digitaltruth-- and were harder to
print --and still gave me no good results--.

delta3200 gave me nice --or, at least, usable-- results even when
pushed 1 or 2 stops.

hope this helps.

regards,
