Friday Face Off: Mercy

I have Rebecca Lim's debut fallen angel novel, Mercy, in my endless TBR stack, and am eyeing it for an August read, I think.  But when I added it on Goodreads, I noticed something:  It has quite a variety of covers, and they bear very few similarities.  To me, the feathery blue paperback version looks like a book about a ballerina; the middle shiny blue-light Australian cover reminds me of a contemporary novel about, I dunno, a girl struggling with something; the last cover with the embossed angel wings is very moody, and so much prettier in person, I can't even begin to tell you.  They all three give very different impressions (to me, at least), and not having read the story yet, I can't tell you which is better suited.
But which makes you want to read it more?  Any inspire cover lust?

Which did it better?

Last Week Month on FFO:  The men of Austen went toe to toe, cravat to cravat, wet shirt to love letter in an Ultimate Swoon Off.  There could be only one winner, and that winner (to the relative lack of surprise of all involved) was Mr Darcy.
