How can you do this to me? How can you open this can of worms? Wretched I am, I deeply apologize. In today's face-off we have two of the biggest male groups going head to head. Who's the more talented group? Who has the best looking members? Who produces better music? Is one more popular than the other? You choose in today's K-pop face-off!

MBLAQ, Music Boys Live in Absolute Quality, was created by solo superstar Rain and consists of members Seungho, G.O., Lee Joon, Thunder, and Mir. The group debuted in October of 2009, the exact same time that B2ST also debuted, with their single "Oh Yeah." The group hasn't reached the pinnacle of their success just yet and have had a difficult time proving their worth in the industry. Nonetheless, in 2010, they won the Newcomer Award at the 2010 Bugs Music Awards, the Disk Bonsang at the 26th Golden Disk Awards in 2011, and the Best Korean Artist Award at the 2012 Asia Song Festival in 2012.

Aside from the boring stats, let's take a look at the fun facts. The group's most popular member is Lee Joon. Known for his quirky personality, ravishingly charming looks, and body, Lee Joon is definitely the face of MBLAQ. 2NE1's Dara's younger brother Thunder is also a fan-favorite followed by G.O. and his ex-beard. The group is loved for their good looks, Seungho's vocals, G.O.'s facial hair, dance moves, and charm.

When B2ST first debuted, I don't think anybody expected them to be anything like what they have become. Firstly, the group consisted of two axed singers, Yoon Doo Joon and Jang Hyun Seung. The group also added on once solo singer Lee Ki Kwang, known as AJ in the past, into the mix. To everyone's surprise the group ended up being a huge success. Off of their first full-length album, "Fiction and Fact"their huge single, "Fiction" received the triple crown on M.net's "M! Countdown"and got the industry buzzing. They won the Bonsang award at the Seoul Music Awards in both 2011 and 2012, Artist of the Year award at the Melon Music Awards, and ALbum of the Year at the Gaon Charts Awards.

Fun facts about the group! The group's most popular member is the handsome and very short Lee Ki Kwang, followed by cutie pie Yoseob who reminds me of a Smurf and an adorable elf smashed into one. The group is known for their personalities, stage presence, addictive choreography, and hit singles.
