Placement should be almost entirely based on performance of the players alone; it should be in the kids' hands to win or lose.
If two units are deemed equal in terms of demand and execution, then the nod should go to the one who better connects with the audience, the more entertaining corps.
Design of the show in and of itself should have no impact whatsoever, since I've learned that some of the best designed shows are often things we have no interest in seeing and, other than maybe other designers, who really cares? If the audience is busy checking their watch or sitting on their hands or rolling their eyes, how is that a good thing for anyone? If people are leaping to their feet, screaming and throwing babies, that is obviously good for everyone. ('cept maybe the poor babies)
