You are definetely right. However, efficiency is meaningless without
reproducibility. For the molecular set you have used (rigid and small
molecules) reproducibility is not a problem whether one uses FEP or NE
techniques.  However do you feel that your conclusions on
computational efficiency for benzene or ethanol hydration energies
apply unscathed to monsters such as the MCL1 inhibitor S63845 (
