Larry,
When I loaded only Korg factory resources on both my PA600 and my KMA I was still happier with the out of the box sound of the KMA over the PA600. I don't know if I would have sold the KMA but did think about it. John's resources did not work on the PA600.

There is a lot of difference in the type of styles and the implementation of them between the two keyboards. The KMA fit best what I do on gigs. With John's resources it became a real winner for me. He apparently spent a lot of time adjusting not only styles but the sounds associated with the styles on the KMA. i actually use the KMA as a stand-a-lone keyboard on gigs. It gets a funny response from the audience. I show them the really small keys and hold it up in one hand and when I play it everyone is amazed at the sound from such a small instrument. It is also a wonderful tool to travel with - very small and light.

The thing with Korg keyboards is if you want to replace all the factory resources you must unlock them in the global settings then load the resouces you want to use. Otherwise only part of a set will be loaded and you are not really playing with the complete set you attempted to load.

It is a bit more work but even without a songbook feature it is rather easy, but time consuming, to setup separate gig sets and copy them to a SD card.
