We've been using both in the shop. I think energizer is a better overall cleaner, especially if belt marks need to be removed. We're finding that the foam is better suited to cleaning dull surfaces after the oil is extracted. I use the foam as more of a secondary applicant after Energizer or a spray nine treatment.
