If you prefer accuracy over throughput then Prodrug/gromacs minimization
and dynamics could be a choice. Autodock uses its scoring function
which includes force-field terms and empiricaly derived terms for solvent
effect and conformational entropy of ligand. Therefore only force-field
energy itself (either from gromacs or autodock) can hardly be a better
for scoring of ligands. You might try free energy calculation by linear
interaction energy (g_lie of gromacs).
