Arsenal (least he's got two arms)
Shazam (still ongoing, but already way more interesting than pre-reboot CM)
JSA (Earth 2 is kicking so much more ass than any of the recent JSA titles)

Vandal Savage (c'mon, this guy ROCKS in Demon Knights!)
He's temporarily in prison, but I would say Penguin. He gets a piece of every crime that is committed for profit in the entire DCU. He's collecting from African warlords, mob bosses, corporate executives, and street hoods. Not to mention holding some of the most dangerous weaponry in his vault like Freeze's gun.
Red Hood without a doubt, he finally has a purpose and is a real character instead of a plot device.
