What's Your Favorite Re-Design of the DCnU Reboot so far?

The first 52 issues have all been released as of today. We've seen some major changes and some subtle ones. Out of all the redesigns so far, what's your favorite? It can be costume changes, personality changes or a mix of the two. My favorite so far is Superboy. 
I love his new costume and I love the fact that he's going to slowly develop his personailty and heroic attributes. He is a clone after all, so it makes sense for these things to take time. He shouldn't pop right out of the proverbial test tube with everything established.
