Which guitar should i get???please help?

Well, if you hadn't noticed, the first guitar is actually a reproduction of A7X's guitarist's guitar. Synyster Gates. I'm guessing that would be best. Especially since one of the bands you mentioned is Avenged Sevenfold. Hope I helped! One good thing to do is to look up reviews on YouTube and listen to people play songs on it. Provided that you can use YouTube of course.
