I think Carlile and Esme definetely, she is so lovable to all and each of them, Carlile is very understanding guy, don't you think?
The best Cullen couple is... Alice and Jasper! They are so alike and yet so different; they balance each other out. If not for Alice, Jasper would be miserable and lonely because he would have never met the Cullen's if not for Alice.
