For example TXP and HC 110 are complimentary, the film and the developer naturally lean toward the same type of curve, a long beautiful toe and great separation of tones middle to high. It is a classic combo. TX/HC110 similarly.
Delta or TMax in DD-X or TMax developer will have a shorter toe, better separation in the shadows, but the straight line may actually be slightly flatter, so the mid to high tones might look flatter, if developed to the same CI. These are "classic combos" too.
Adjusting the CI to match the "snap" in the mid to high tones of TXP/HC110 or some personal best CI would provide a more practical result, a better demonstration of character.
