Points here: 25% for cost across three years, 25% for coverage of the price and 50% across renewal terms, state-by-state fit and pricing clarity. Massachusetts came down to coverage of the price.

The Mainstay agent plan earns more coverage points: papers served on the company are scanned the same business day for free, one price holds in all fifty states and three government mailings a year are scanned at no charge. MA Registered Agent.org wins on cost, so the two finish close.
