Best Non-Nexus AOKP, Cyanogen etc Phone?

Okay, so the Nexus 4 is too tough to get, and I don't care what people say, I don't like the glass back. I'm too clumsy.

So, which non-Nexus Android phone is best? Which can be modded with a ROM that is the best, easiest, most complete, most current? I am not keen to do this and find that the camera, for example, is not fully functional.

Added twist, I don't want a Samsung SIII. Everyone has a friggin SIII. I want to be different for the sake of being different.
