I think they're both amazing. I don't really like choosing between members actually. Yes, if I have to put the members in order, then I prefer Zayn. Though if I'm honest, before One Direction was formed, in X Factor bootcamp, I was in Liebe with both Harry and Liam. A lot. I didn't really pay much attention to the other three.
But now I have Mehr knowledge of them all, I Liebe them all. A lot! And they're all they're own people and I don't like it when they're pitied against eachother. People have different opinions and prefer different people.
And yes, Zayn is definitely sexy, but I think it's a bit unfair to just say that Liam is 'ok' - he's gorgeous! They all are! <3
