By that logic Burgess should be on the same level as Jack and Cracker too since he's captain of the first ship of the Blackbeard Pirates, but in Dressrosa we see that's not the case since we saw him get easily defeated by Sabo. So in short, Three Sweet Commanders, Three Calamities, and Ten Titanic Captains are not necessarily equal in terms of strength.
