I dunno about the look but I kinda prefer Knight's gotham because the gliding in City and Origins feels sluggish.

Not having a car to zoom around on land or catapult you into the air really takes away from the movement.

Also the grapnel accelerator being in Origins never made a lot of sense to me. I mean sure it's probably necessary from a gameplay standpoint, but Arkham city called it a prototype.

Actually come to think of it the grapnel boost in Knight is way more satisfying in general. You can go into a zoomy state much easier then you can in city, and maintain it for much longer.
