That's actually another tough question. xD But...

I'd definitely have to say Arkham City. The environment was much larger and you could do so much. So much endless possibilities! The riddles and trophies are more challenging and actually involves a little bit of clever brainwork. I won't say I hated the ending boss fight for Asylum, but I thought it was too easy and deserved more of a challenge. Right now I'm working on getting Batman full upgrades on everything before I start NG+. I heard that Penguin and Freeze were a bitch to fight on Arkham City NG+ so I want to prepare myself in every way I can.
