Batman: Creature of the Night (even just 50% out, it steals the top spot)
Super Sons (more a "Super book", but still my favorite ongoing at the moment)
Batman
All Star Batman
Nightwing
Nightwing: The New Order
Batman Beyond
Detective Comics
Trinity (with a significant gap between this book and the ones above)
Tradewaiting on Batman: White Knight, but I expect to enjoy it as much or more than Sean Murphy's last solo outing, Punk Rock Jesus.
