It all depends how you will make your exposure and which choice of developer you will make.
TMY-2 looks very smoothly and grainless when using Tmax or Xtol (box speed). Tri-X (E.I. 250) in Rodinal has tight but regular grain.
T200 in Xtol is also very smoothly, almost without grain and a large grey scale. In Rodinal/R09 you will see the grain, even clearly but the film is very sharp. To improve contrast use a yellow filter. It works nice on the T200 film.
