On an anecdotal basis, I relied on the Taiwanese National Health (NHI) for years and found it vastly superior in terms of quality and cost to the United States.
Perhaps a more accurate claim might be: The quality of the health care system in the U.S. is unparalleled provided that you are in the 1% that can afford it.
