I don't think I have a choice. I am part of the State of Michigan Teachers Retirement System. Right now, as I said, I get my insurance through my employer. It has been excellent so far, except for the ridiculous battle over Cadodex (they quickly gave in when Dr. Scholz contacted them).
When I re-retire, I go to the State Plan. That keeps changing, so I'll have to see what they have. I know they piggyback on Medicare
