Does Perceptol possess as much acutance as Rodinal?

Is the grain truly that much finer than Rodinal?
Perceptol has a LOT less grain than Rodinal. Well, so do XTol and all other developers. If you want grain try APX 400 in Rodinal and push it to 1600.

Ilford Perceptol alias Kodak Microdol-X is not too bad in terms of acutance, and it becomes pretty good at 1+3. But with most films you lose some speed. And of course it is not as comfortable to use as Rodinal and does not last for centuries.
