Which cover of "The Fifth Child" is the best?

In my opinion, the second cover out of the four is the best one. I think this is because throughout the book they are freaked out by Ben's image. Especially when he was first born because they were used to having children whose images were absolutely perfect in their eyes. But as for Ben, "He's like a troll, or a goblin or something." He was thought of as a goblin or a troll because of the way he would crouch down when he was about to get into some trouble. He scared his mother, father and his siblings with every move he made. When Ben wasn't doing anything at all but looking around, he was still the center of attention, and not in a good way at all. On the second cover if you look very close you can see Ben crouching, but the overall picture that i believe most people see is the face of a monster. Both of these images describe Ben very well, which is why i feel that this cover is most accurate in describing the story.
