Which demographic would give better marriage advice, someone who has been divorced repeatedly, someone who is married, or someone who never married?

I know what my vote is, people in a successful marriage would have the best advice. It's plain stupid to listen to someone who has been divorced, and even more so if said person has had multiple divorces. And single people who can't get a significant other are just as bad.

Reason being the last two are miserable, and they want everyone else to be miserable.
Person in a successful marriage.
Person who has divorced once or multiple times.
Person who is perpetually single.
