For me, the AR seems a little less playable? That is, when the AR is on, the pokémon stands still in the real world although my phone may move, while when the AR is off, the pokémon stands still on my phone screen no matter how my phone moves. ~shrug~
Addendum: On the other hand, it may well be all in my head. :-) The AR uses more battery, so I'll say that's why!
