Well, just point me off to a few and I'll get back to you.
No doubt the Wersi can sound more live and full than a Yamaha... hard NOT to, in all honesty.

It's the guitars and basses that I haven't yet heard better, at least in style mode. Are there any demos that head to head some of the unplugged styles, the picking patterns and strumming stuff?
I'd like to hear it a bit more naked...
