Take those 4...or 5 or an infinite variety of parameters you probably haven't considered...and multiply them by the number of people on the planet and you'll come close to the number of parameters you have to test.

Sorry to say but there is no test or measurement that you can apply to say that one saddle is like another. You are the biggest variable in the equation. How you ride, how often you ride, your level of dealing with discomfort, etc., all determine which saddle is "best" for you. No one else can tell you what saddle works.

That said, a lot of finding the "best" saddle comes down to you adapting to the saddle. Saddles...even Brooks...don't "break" in. You just get used to their idiosyncrasies. In other words, you break into the saddle.
