Medicare Advantage Plans and Medigap plans existed before the ACA [I worked at an insurance company 10 years ago]. Only time will tell what is going to happen and even without the Texas judge, any law can be 'tweaked' at any time so one cannot rely on the current law to be around next year, 5 years from now or whenever in the future.
I currently have Medicare and insurance through my work so I don't have an Advantage or Medigap plan though I will look into them when I decide to quit.
