I would say a grille delete or outside smooth cover would be the most efficient in aerodynamics.

air stuck in a pocket will allow air to pass over it. think pickup truck bed. not the most efficient but better then nothing and sending turbulent air into the engine bay and out under the car and in the wheelwells.

the new ford focus that has a grille like this. has ducting that goes to both sides. I believe releasing the air into the wheelwells or up the fenders to the cowl. I will try to get under my brothers and see where the ducts go exactly.
