I have had cameras that used AA batteries and the lithium rechargeable.
I would choose the camera that came with a lithium battery every time........the only advantage of having a camera which uses AA batteries is that they are freely available almost everywhere........but the disadvantage is the cost.(camera's need quality AA batteries to run them...like Duracell...not cheap)
I always have two batteries with me......and when I buy a camera I always buy an extra (camera specific) lithium battery as a back up.
