Madonna's performance was lame. She has a great discography and that's the best set list she could come up with? Not to mention she gave GAYL way too much attention and chose terrible guests.
BruNO got the best recurrent sales for any SB act thus far, so he still wins.
Ofc Bruno delivered the best performance quality-wise, singing live and everything. But Katy benefited from a very interesting (for the americans) match and so many props and visual effects that dazzled the viewers simple minds. Since I don't expect Bruno do attach himself to a flying star or to dance with animated sharks and palm trees, I am fine with it.
