What transformation method will be best suited to convert the datum from NAD83 to NWS84?
Do you mean WGS84 also known as WGS 1984? Try NAD_1983_To_WGS_1984_5. If the data is in the lower 48 states (except maybe the west coast states) and accuracy is a meter or more, try NAD_1983_To_WGS_1984.

No, I am looking for transformation from NAD1983 to NWS84 (Radius 6370 km spheroid).
