Having had a marriage extension and a retirement extension I can say unless you are planning to have children or cannot afford the retirement extension (400K/800K) the retirement Visa extension is the way to go. Much less paperwork and you will not be controlled by your wife if things go bad.....Divorce would negate the Marriage Visa extension.
every democratic civilized country in the world other than Switzerland has socialized medicine, the USA has Medicare, Medicaid and the VA which are socialized. In Switzerland there is no piece of garbage private insurance like Medicare Advamtage.
