I sell all the big guys, and each company has their strong and weak points.
I love the PA series, but there are allot of styles that are missing, and I don't like how the fills can not be activated when hitting a variation, ex fill to variation, they have some work around but not to my liking.
Yamaha has great styles, and plenty of them, covering everything, hate the latin section, but they are 2 short, most of them are 2 measures long. vocalizer/mic input is sub par. great solo voices, but they don't have an easy way to select right hand sounds, if your playing a style that has 1 touch setting all set, and you want to play a sax, you have to make sure you have the selected R1, and turn off the others if they are on then select trumpet. Korg has Performances which has everything from layers to effects all set.
The Audya is a very expensive piece of machinery, but so far the company has been helping to mold it with updates and addtions.
I'm not saying this will be the best, but they are trying and hopefully get closer to it's value
