The scrubbie setups I have seen don't seem to break up the streams of water very well. Water seems to find paths through the scrubbies and stream down those paths.
Bio Balls seem to break the incoming stream of water down to drops of water very effectively maximizing the air water surface area and gas exchange.
I use Bio Balls.

rate as they spread the water so thin, but are basically useless as submerged our partially submerged media. Scrubbies work well for both setups imo. If people would read the op first post then money wouldn't even be talked about...people are so eager to respond but don't read...tisk tisk!
