why some ex-Muslims convert to other Abrahamic religions instead of leaving religion entirely?

Hello everyone, this is a question for ex-Muslims who have converted to another Abrahamic religion: Why? What convinced you?

It’s really strange to me because all Abrahamic religions have the same rules and values if you actually read their books. All the ex-Muslims I know are atheists, so I didn’t know someone could consciously leave one religion for another.
