The manufacturing process of OSB eliminates voids that are typical with laminate plywood. The consistency of the product along with the cost savings would make engineered wood sheathing a viable option.
Here in Florida, because we are susceptible to Highwinds, wraps are important. I usually find 4 to 6 nails per wrap even though the minimum is three. It is necessary to check several sides of the house to find the weakest link.

Chinese drywall
During the housing boom between 2004-2007, many southern builders imported cheap drywall from China that contained fly ash, a toxic substance found in fireworks. This material was used in about 100,000 homes in the US. It may cause respiratory ailments and may smell like sulphur. It is very difficult to tell if a home has Chinese drywall but there are several indicators one can look for like exposed copper wiring turning a dark and corroded color. This drywall cannot be repaired and must be totally replaced. It has costs some homeowners many thousands of dollars and there is currently a lot of litigation pending.

These particular windows did not meet the requirements so I noted that on the report.
