this is a toughy!! i would like to say niall cuz he is so nice and has a great personality! but at the same time louis is so funny and great! so i'm torn!! i think its a tie! Niall and Louis are equally sweet in their own different ways!
i love them both. but i would probably go with Niall because he is just so adorable but Louis is so funny, which i think is sweet, and that's what kinda guy i like.
