Super curious situation. I'll start by saying nobody really knows what to expect, myself included. With that out of the way I expect the differences to be: GSO-world famous fit and finish with a wider selection of steel, handle and sheath options at the expense of waiting a long time to get it. SK-unkown (but still good) fit and finish with limited materials and (I pray to the entire Greek pantheon) a much faster turn around. I interpret this as "paying" for the better product line with your time rather than money. As S!K gets caught up as they plan on doing, the wait won't be as much of a difference, the quality control and options will be.
