Great question!
My DD(almost 4) only throws tantrums at home and she is the perfect angel at school. She is very whiny and emotional at home. It's to the point of pathetic. She must really know she is loved!
My DS5 was the opposite--not many fits at home but he got in trouble constantly with his preschool teachers. I think it was a lot of the power struggle with authority. Since changing schools we see a lot less of this power struggle since he is more challenged and he does witness a lot less social injustice in Montessori.
