Although I can't see Ron and Hermione as a couple, I'm going to have to say that their Kiss was better, mainly because I cracked up. Harry and Ginny is one of the WORST book couples ever! Whenever they kissed, all I did was gag!
Ron and Hermione of course! It's the most awaited snogging in the whole series! I mean well, Harry and Ginny have already kissed, but Ron and Hermione have only gone through other terms of affection and is yet to have this one moment of romance.
