Justin Timberlake vs. John Mayer

Although Justin Timberlake and John Mayer differ greatly in the music they make, there's no denying that both artists are incredibly talented. Thankfully, both musicians have released new music this year, and as we enjoy it, we're wondering which singer is more swoon-worthy.

Justin Timberlake is a force in the entertainment world. Singer, dancer, entrepreneur -- he's got it all. The star, who was honored with the MTV VMA lifetime achievement award this year, also turns it out on the red carpet. He's always dressed to the nines and has a charming personality to match.

John Mayer has transitioned from playing acoustic rock to adapting a bluesy sound. However, his knack for heartfelt lyrics has only grown better. Once touted by Rolling Stone as a "new guitar god," the singer has also written columns for Esquire magazine.
