What decided the ranking
Five criteria set the order; the two heaviest are three-year cost and what one price covers. Here three-year cost made the difference.
At $297 over three years, MD Registered Agent.org saves $150 against Mainstay Filing. A Maryland-only company gains little from coverage elsewhere, so cost won.
