If I'm not mistaken, 'Just Dance' is one of, if not the highest-selling debuts of all time. Not to mention it was a global smash, whereas (I think) AATB has been mostly successful in the west. But I guess we'll have to see where AATB takes Meghan. JD catapulted Gaga into the stratosphere and despite AATB's success, Meghan isn't as known/cared about/fawned over as Gaga was at the beginning of her career.
