Hi Spalding
Pity the weather was a bit of a washout over the weekend, still hopefully you had a good time.

Back to the post:
Personal preference will be different between users, (Hence my post of how do you define better) however may I make a suggestion.
The Korg is an excellent controller keyboard, and there are some excellent free VSTi available, (Check out http://www.kvraudio.com/ ) so load the VSTi of your choice on to your computer, then connect your PA1x to the computer to control the VSTi, that way you will be able to directly swap sounds, and see how easy is it is (Or not) to adjust them.
Obviously you will not be converting a style, but it should give you a good idea of how it works on the MS, and as you are setting it up, there is a better chance of getting the correct sound that you want. (You could have 100 or more different types of steel guitars available with VSTi, so it would be pot luck as to whether another user would choose one that just happens to suit you)
Hope this helps

Bill
