I use both and both hold fish. If you place them close together the brush will hold more fish. If the're isolated then they will both be about equal, however, the average fisherman can catch more from the condo. Why, because he doesn't get hung up as much. A good fishermen will catch more from the brush most of the time.
When I'm teaching I prefer Condo's. I can teach the angler to let the jig sink and swim it thru or just over the condo. On brush most anglers fish to (fast) shallow over the brush or are constantly hung up in it.
