Dear Arso,
So why did The Rebbe waste resources on the Litvishe Yeshivos? Why did he get so involved in helping Israel? Why did he help out Kashrus Organizations that were competitors to Chabad ones? Why did he shy away from most of the controversies in the Torah World?
I don’t know how to compare him with the other gedolim of his generation. It is clear to me from his correspondence that he wasn’t as proficient as Rav Moshe Feinstein. But to his credit, he very much considered Rav Moshe’s word binding on the people (for the most part) and he refused to have any part in attacking other gedolim. That to me, is a major sign of a leader.
