You tend to claim that there are these great differences, but I have yet to see a source.

That's because I don't cite the names of sects in my notes. 
One great difference is that apparently there are sects that only have 3 archangels, when the most common version is that archangel is one of the classes of heavenly beings, in Christianity the top rank whereas it's in the bottom... I think it's the third lowest in Judaism? Definitely in the bottom five. Just checked, it was third lowest. Only above Angels and Powers.
