Miley was disappointing, Katy was B A S I C , I like Justin but his performance was only good because it was long & they were mostly throw back songs & n sync, & obviously Gaga's was the best who else can have 3 amazing wardrobe changes like that on stage.
It's too hard to pick! Obviously have to eliminate Miley since she was beyond inappropriate. But to me, Justin since he's had more time in the business. I love all three though.
