Can't really compare the two. One was a nation state, fully mobilized, following a political and racial ideology, bent on world domination and enslavement by means of taking land and resources. Conversion of less desirables into slave labor.
The other is a religious ideology, guerilla style fighter with no nation/homeland, bent on world domination of religion. Killing the undesirables or converting them to the religion at the point of a sword.
They share a few commonalities in that they both hate(d) Jews and would eradicate them as a people. The Germans controlled the ROP in Bosnia and eastern Europe during the war and used them against the Jews. They did not try to convert them from their religion, but they wouldn't hesitate to execute them either. The ROP wouldn't hesitate to kill the Germans if given the chance today, but would do it because they aren't of the same religion.
But it would be a fun fight to watch.
