i think that harry is better because harry is a funny and charming guy and has a tiny bit meer potential than louis and plus his hair makes him unique :)
I honestly think Louis is better because of the way he acts. He acts like an immature child, but in a funny way, and if he were to have to be serious about something, he would be serious. Sure, Harry is sweet, charming, and nice- same as Louis- but I feel that Louis has that little spark that, I don't like, brings him to life.
PLUS (this is from 1-D self) HE IS FREAKIN' SEXY AS HECK! LIKE OMG OMG OMG! AUGGHHH HIS SEXINESS IS LIKE GOING TO KILL ME! SOMEONE CALL 9-1-1!!!!!
Louis all the way! He's so sweet and funny. And just seems to enjoy life to the fullest, not to mention is very, very outspoken. But I love Harry too! Oh, those gorgeous green eyes. And how mature he is, and also a supporter of veilig sex!
