Hi Seamaster
Posts 4 and 9 are Yamaha Tyros 2 styles not Wersi styles (I made a point of this in the relevant posts)
From what I can gather like me, you are not a Yamaha style fan, I prefer Roland, Korg and Ketron styles myself.
As for comparisons with other arrangers/organs, do a search for keyboard festivals on SZ and you will find I do full reports on them, which includes listening and trying all the keyboards/organs on site.
Regards

Bill
