Which Green Lantern is Batman's favorite GL?  Which Flash?

To segue, I'm really enjoying Batman: The Brave and the Bold.  A lot of the Timm-era shows worked hard to make the silver-age DC villains make sense and seem imposing within a modern context.  B&tB's lighter tone lets them look as cheese-tastic as they were meant to be.  Also it throws out plenty of great references to elseworlds stories.  Jeff Bennet is an awful Joker though.
