Of course with clever programming of your controller, you can get a "Desktop Experience" and maybe even more
Indeed I have the Snow because I don't need the extra polyphony and I don't like having a bulky rack with a bulky controller (so uncomfortable, for this I prefer the Polar). The snow is perfect for the small footprint and usually I prefer controlling it just with the controller and keep to a minimum any direct interaction with the Snow. So for me the smaller, the better.
