US // UK
Eh... I'm not really a big fan of either of these covers, though I own them both. As much as I love the actual book (my name's in it, i'm pathetic -- enough said), the UK cover is pretty dull, even in person. I think there's too much black. The US one makes me think of a TV show or movie, though it is marginally better.
So, I'm in the middle this week, with a slight lean to the US side. How about you?
