The Voice: The judges don't see the contestants until they hit the button on their fancy spinning chairs, signaling their interest in having that singer on their team.

The Voice: "You have a great sound; you're developed. Cee Lo has another meaning for the word 'developed' when he talks to you." — Blake Shelton
X Factor: "It was like, imagine I am a factory in China, and I've been given an order to manufacture 10,000 Justin Bieber dolls that sing and dance, but it kind of went wrong in production. That's what you are. It wasn't quite right." — Simon Cowell

The Voice: Last season's playful sparring between Christina and Adam came to a head when she slammed his contestant (and her former fellow Mouseketeer) Tony Lucca during the finale... their rivalry alone is worth watching for. Well, that and to see what other spherical object Christina slaps on her head and tries to pass off as a hat.
X Factor: Britney Spears has already reportedly stormed off the set once. What other shenanigans can we expect from the explosive star? If she ever shows up sporting her shaven dome of days gone by, it's on like Donkey Kong.
