Yes, it subjectively more objective.

(Like, I’m making a cute response here, but there’s not exactly an objective standard for objectivity, when you come down to it. Turtles all the way down and all that.)

Much more so than academic accreditation.

Anyone can come off the street and take a bar exam. Not everyone can afford the time and financial burden of attending law school.

Probably the most objective standard for becoming a lawyer that there is. More objective than the hiring process and law school and college admissions, especially when many of these are de-emphasizing standardized testing.
