It seems to me that the black player who chooses the setup has an advantage to his white opponent who doesn't know what will be the setup.
It is true that the black player may know an opening theory for his favorite setup but as they are a lot of possible setups, one would have to know a lot of opening theories which is reducing the impact in my opinion.
