That decision is entirely up to you. Keep in mind though that you do not have to like someone because they like you back or because they are cute. When one actually falls for another person, one will know for a fact that they like them. You should not have to ask who to like or the motives for such things.
we have a saying in mexico and it is: "don't leave the one you love for the one you like, cuz the one you like may leave you for the one he loves" i think that's the correct translation =)
I don't know if you still need an answer seeming as it has been 3 days since you posted it but here is mine.
-I don't think it's a matter of which one should you like but which one do you like. Go for the guy that's always on your mind, the one you can't stop staring at. The one that makes you laugh and the one you want to turn to if you're upset. Just make sure that he's the one that makes you feel good and happy when you're around him and that's guy you should go for. The one that brings out the best of you. :)
