I think Grimm are a lot more resistant to Hexenbiests than your typical normal or even most Wesen, hence why they are feared so much.

Note however how Adalind nor her mom tried to use their powers on Nick or his mother. Fact is, Adalind's mom was very much afraid of Momma Grimm until she was backed up against a wall.

The only caveat is how "more powerful" is made into a Hexenbiest Juliette over the "born Hexenbeist"?
