That's a great guitar video enjoyed it alot, but hated the camera angle ...doesn't show anybody's fingers??
That said, point being here is that most arrangers KB's today can be made to sound fantastic as we see here with the BK9, and many others on the market,.....so why all the mine is better then yours scenarios? ...Play what you enjoy and develop your playing skills to get batter a little more each day.

Thanx for the video.
