Old cover vs new Cover

It's s little while since I've done a covers post.
Here are some covers that have been redesigned for re-release - which do you prefer old or new?

What's interesting about these two, is that even before the re-release (below), there was a change in approach. 

  Re-release (below) has a much more suspense feel. I haven't read these so I can't tell you if that seem like the right approach. However they are YA, to me the original (top) covers seem more YA, maybe they are trying to broaden there readership?

This is a redesign of a much older cover :)
