There is almost no actual Kobe beef in the U.S. Unless you like fat you would be happy with a Wagyu steak. Most steaks in the store are USDA Grade Choice or Select. Good steak houses are Prime or High Choice. Wagyu would likley be about 2 Grades fatter than prime and kobe is usually about 2 or 3 Grades fatter than Wagyu. As a Montana carnivore I would have no interest in kobe beef. My suggestion would be try some given to you. There are many producers who think they have something special and are willing to give you a sample, about like Walmart used to.
Hope this helps you out.
