They both suck balls and they aren't even good, if wewe want to hear a band with REAL muziki then try listening to this singer who is the lead vocalist of two bands. His name is Tim Lambesis.
Oh your not going to like the majibu people give wewe kwa asking this.
For their muziki they both sing bad in my opinion. For how they act I would say One Direction because after what Justin did I will never respect that guy. He doesn't even deserve to have mashabiki after what he did. Honestly,personally I prefer 1D outside the whole muziki thing.
