Well, that's PART of it... being tailored for the European market. There's a lot of us with money over here in the US. And we don't play schlager!

But I saw nothing in the specs about having a fully integrated soundset. Looked like a laundry list of different, mostly not TOTL sample sets to me. I am just not sure how many people realize just HOW complex a task making a comprehensive, COHERENT soundset actually is. It's not just a case of finding good sounds, it's having them so the ALL work the same way, blend together sonically and EQ-wise, all respond to velocity and controllers identically, and all the other things that makes a soundset. Arrangers essentially set out to have sounds set up that, you replace ANY sound with any other sound, it's essentially going to WORK (or at least not stick out like a sore thumb). I've never worked with a software product yet that fit THAT bill...

You can stretch a lot of mileage out of a good style by re-voicing it. Change out jazz guitars for acoustics, change pianos into Rhode's, change stick kits to brushes, or rods, or hands, change electric basses to synth basses, you name it. String lines changed to woodwinds, saxes, whatever.

Without a soundset that makes experimenting with doing this a painless operation, you are less likely to try. Or succeed. I wish more people were appreciative about what an amazing job most closed arrangers do at a task that seems to have eluded most software sampler makers.
