Best Android smartphone on AT&T?

I've been anticipating my first phone recently, and have been doing some research on which Android device I would want to buy. I was dead set on on a Galaxy Nexus, as it is (IMO) the best Android device out there, and fits me well. I recently discovered that AT&T (my carrier) does not support this phone. So I was wondering what the closest phone to the Galaxy Nexus would be under the AT&T carrier. I would prefer one without a keyboard, and one that can run games well.

TLDR: Best Android smartphone on AT&T

Edit: You guys are the best, this made my day. I can't wait to get my Galaxy Nexus. Upvotes for all!
