That depends on the dilution. Both developers are solvent developers. Higher dilution will reduce the solvent effect, increasing grain and sharpness both.

All things equal D-76 is slightly higher quality (sharpness at a given level of graininess is higher) but you can't really get rid of grain without getting rid of sharpness (unless you minimize enlargement or go with slower films of course).
