I own both. If you are going to be dealing with Korg styles only, then KAT2000 is a better bet. You can download a demo of it and try it out.

So far, Klaus at EMC Styleworks has not been successful in implementing the Korg paX1 style format into Styleworks. It doesn't handle the paX1 styles properly. So it might not be something for you. However, I do think you can download a demo of Stylworks as well.

You should try both demos to see which fits your needs.
