Another month, another (friendly!) K-pop rivalry.

As of the past week, both GFriend and Brave Girls made their official comebacks with "Fingertip" and "Rollin'" respectively, resulting in a massive amount of fan support for both troupes. While GFriend opted for a strange, dream-within-a-dream mystery concept for their catchy retro bop, Brave Girls went the sexy route, resulting in a 19+ rating on their seductive, but still relatively tame clip for their Tropical House-inspired tune.

During Brave Girls' album showcase in Seoul, the girls were asked who they consider their rival group to be, to which Eunji responded "GFriend," telling a story of how her younger cousin doesn't know who Brave Girls are, but does know GFriend's songs and choreography. (Ouch!)

So here's the question: if they are friendly rivals, which group is your personal favorite? Review their March comeback clips above, and then place your vote. We'll reveal the results right here on March 15.
