The only difference between Satmar and most of the other Gedolim was how to deal with and interact with the State post facto. [maybe]
The difference however is very major.
satmar , ujm , katan and somejew are not concerned about the safety of millions of innocents , yoshvei tsion.
whereas most other gdolim i.e. Agudas Yisroel, the Litvish and the other Chasidish all , are concerned about the safety of millions of innocents , yoshvei tsion.
