The main difference for the user is that Phenidone is less stable and not as easily going into solution in water. OTOH, it is a little more active, as a rule of thumb you can replace Phenidone with about 20% more Dimezone-S. Xtol contains Dimezone-S, the typical copper colored solution after giving Part I to the water comes from Dimezone-S. It will get colorless after adding ascorbic acid and sodium sulfite. I routinely use DS-10 from R.Suzuki (http://silvergrain.org/Photo-Tech/film-dev-recommend.html) as my main developer for films like the Deltas, Acros and 400TX. Extremely fine grain and good sharpness.
