I would place FG-7 (1:15 dilution) with HC-110, or slightly to its right...
But since I would place the above developers on a bell curve in terms of sharpness and tonal "niceness" (with D76 nearest the top of the curve),
I see little use for the others, except maybe when convenience is paramount.
I do use Acufine for fast films (and TMX) when maximum speed with near-normal
tonality is desired, and would place it with FG-7 on our grain and
sharpness/tonality curves...
Hope This Helps
