The scan looks great!
Are you worrying about the Quality Score dropping from 97 to 90? Well don't!
The Quality Score is almost meaningless anyway, and certainly cannot be compared between drives that report PI/PO errors in different ways (e.g. per 8 ECC blocks for the BenQ compared to per 1 ECC block for the BTC).
Your BTC scan is reporting very low PI Errors as well as PI Failures that are within spec (PIF per 1 ECC block <= 4).
