The Edwal FG 7 has lower solvent action than D-76, a common practice was adding sodium sulfite to FG 7 to adjust the solvent action, this is finer grain and slightly less sharpness.
Also the FG 7 is slightly more compensating than D-76, but this can also be adjusted by concentration and agitation.
FG-12 had more solvent action than FG-7 (if no sufhite added) or D-76. I cannot tell about shadow detail, for shadow datail I prefer Xtol, as it has some 1/3 stop advantage in shadows, TMax developer has even more shadow detail than Xtol, but more grain.
