The answer, of course, depends on your system under study. It's fairly
common practice, at least for protein-ligand binding in globular proteins
to use the ACE and NME capping groups to avoid adding charges when large
gaps exist in a structure. This is preferable, in my opinion, than using
the neutral patches which may produce spurious h bond donor/acceptors.
