To merit to fear of God and to good character traits was a major point of Rav Israel Salanter. [I mean that was the major point of the Musar Movement.]
I think the main benefit of Musar is the formation of ones consciousness plus world view issues.
That is to say that without Musar it is easy to adopt false sets of values all the while thinking sanctimonious thought about how one is keeping Torah.
Musar has the advantage of having its background world view being Platonic as outlined by Ibn Pakuda in the beginning of his Obligations of the Heart. [And that world view permeates most of Musar of the Middle Ages.]
