XG sound module

I could use some help here... my question is:
What sound module does Yamaha make that has full XG sound set compatability?
I want to play styles (.sty)on it.

I know a QY-100 is, But what others are?

I was hoping the new Yamaha Motif XS rack was?

I have tried the XG softsynth, but I really want better quality and something in a hardware sound module.

Thanks,
Lee
