I use brush piles for refuge/habitat for my forage fish. Downside of that is it has to be replenished from time to time and it adds nutrients that FA just loves to utilize. I am not familiar with either product you mention but, if the goal is to provide refuge/habitat for the forage fish, IMO I would go with the one that simulates a brush pile, i.e. provides the most irregular spacing and most obstructed paths for the predators to maneuver thru.

Just my 1 cent
