Audya has the best live sounding out of the box styles... If you dont eddit much, its a sure choice, still would probably own mine, if it would have been a lot more reliable..
But then my PA3x comes very close to the audya styles.... And it comes with a whole truckload of other things that make playing arrangers much more fun... And the pa3x solo sounds blow the audya away....
But if you just use it for the styles, audya is a prime choice
