The gulf stream would be less efficient, require more passengers and may not be able to land at as many airports. I think they aim for some kind of long-range air taxi. Small groups which want to travel a long distance from A to B but a very short distance to and from A and B's respective airports. Business trips, most likely. And probably the plane is no slouch at medium or even short range if it is operated by a non-airline company. Just not "ridiculously efficient".
