When it comes to performing live, Demi Lovato and Taylor Swift are two artists who really know how to put on a show. While their stage performances may involve very different concepts and elements, there's no doubt that each of these young women know how to entertain their fans. When it comes down to it, though, we want you Lovatics and Swifties to weigh in on which songstress puts on the better live show.

While Demi Lovato may not perform to sold-out arenas all of the time like Taylor Swift does, she certainly knows how to pack a punch with her live shows. Incorporating costume changes, light shows, choreography and powerful vocals into her performances, fans will be dazzled by Demi as she belts out hits like 'Give Your Heart a Break' and other danceable album tracks like the Timbaland-produced track 'All Night Long.'

Meanwhile, up until recently, Ms. Taylor Swift spent most of her nights singing to thousands in arenas all over the world. She incorporates incredible sets into her show, with the stage looking like something out of Broadway play or storybook as she sings tracks like 'Mean,' 'The Story of Us' and 'You Belong With Me.' Like Demi, she changes her costumes up as well, and she also made it a habit to bring out super famous special guests to perform with her, singing with everyone from T.I. to Justin Bieber.
