Dear John,
I don't know how different the RMSD values are, and whether the
calculated estimates are with or without hydrogen atoms (this can make a
difference). In principle, both programs use the Engh & Huber
stereochemistry library, but I've observed in the past that different
programs used slightly different "implementations" of this library,
resulting in different RMSD values, although they should all be the same ...
Good luck,
Dirk.
