I really like both, because Niall has really pretty eyes, I love his hair and from what I saw from their videos, he's a really nice and funny guy!
And Louis is good looking and has a REALLY cute smile.
He is soooooo funny, has an amazing sense of humor.
So I consider them both equal!
I like them both but if I had to choose one of them as my favorite it would be Louis because he has an awesome sense of humor and a really cute smile. Plus, I love his singing!!
