What Is Your Favorite Series Of USPS Stamps This Year?

I need to order some stamps for our upcoming cancellation. I'd like
to get some opinions on the most popular series of commemoratives
so far this year.

I appreciate your feedback.

I believe the Cheery Blossoms, Green Energy and Lady Bird Johnson were all 2012 releases.

I'm a little bit different I suspect, I've been trying to do my cancellation collection for things that match the stamp as best I can, or use general subject ones for cancellations that I really like.
Your options have a very wide range of subject matter. From Rosa Parks, to trees to muscle cars. I realize that it's very unlikely to be lucky enough with currently available stamps to match the cancellation, but quite possibly is there a chance of using another criteria other than popularity?
EG: The Florida issue, whilst it's flowers, might be good enough for a Florida issue, versus using a Rosa Parks stamp to celebrate Orange Juice.

I might be in the minority in my obsessive organizational matching thoughts.
