The 2014 Teen Choice Awards were chock-full of killer performances from Demi Lovato, Jason Derulo, Rixton, Magic! and Becky G. While each artist kicked some serious ass on stage, we have to ask: Whose performance was best?

Demi Lovato couldn't have kicked off the 2014 Teen Choice Awards with a better performance, getting the crowd insanely hyped with her passionate and leather-filled rendition of 'Really Don't Care.' And once Cher Lloyd took the stage, we knew we were in for an awesome treat.

Magic! took the stage to perform their smash 'Rude,' which is undeniably one of the biggest hits of the summer. While the Canadian reggae band's performance was toned down a little more than some of the other artists', it perfectly fit the vibe of the laid-back song, and even had celebs like Shailene Woodley and Fifth Harmony up out of their seats and dancing.

Rixton performed a mashup of two of their hits -- their newest single, 'Wait on Me,' and 'Me and My Broken Heart,' the British band's breakout track. The guys didn't just look dapper, they also put on a kickass show, infusing their performance with an abundance of energy, passion and genuine talent.

Becky G was the youngest performer on the 2014 Teen Choice Awards stage, but you would never know it from her awesome-beyond-her-years performance of 'Shower'. Becky G worked that stage like nobody's business, singing her heart out and flaunting some seriously killer dance moves. Work it, girl!
