Highschool of the Dead & Deadman Wonderland have to be on my top picks as well.

Aside from those two im a huge fan of Air Gear which hasn't had a continuation and also No Game No Life.

Air Gear


No Game No Life

Shout out Air Gear, damn I loved that series. The OVAs released after the end of the show were so good, really gave me hope we'd see it animated through the end of the manga (which admittedly got a little wacky but still fun). I really wanted to see Obama President Omaha get animated.

Seeing Obama in Air Gear manga literally gave me hope of it maybe coming back, but sadly it never did

I haven't seen Air Gear, but it reminded me of Jet Set Radio.
