5 Seconds of Summer and Rixton have both covered hits by some of our favorite female pop artists. 5SOS performed a rockin' cover of Katy Perry's 'Teenage Dream,' while Rixton did a stripped down version of Ariana Grande's 'Problem.' Whose cover is best?

5SOS wowed thousands with their epic performance of Katy Perry's 'Teenage Dream,' giving the pure pop song a little bit of a harder, punk edge. There's no question that Luke, Calum, Ashton and Michael always give each performance their all, and the guys' cover of 'Teenage Dream' just further proves that fact: They seriously nail those guitar riffs and drum beats, pouring passion into every single lyric. We love it!

We love Rixton's take on Ariana Grande's smash, with lead singer Jake Roche filling in on Ariana's vocals. Though the full band is in on the cover (complete with electric guitars and drums), the British group's version has a much more eclectic, stripped down feel. The only disappointing part of the guys' cover? The fact that they didn't attempt Iggy Azalea's rap!
