What is a Medicare Supplement Vs. Medicare Advantage Plan

[jori]

Medicare Supplements simply put keep you with your Part A and Part B which covers your Dr and Hospitals and generally if you have Plan F picks up 100% of the 20% Medicare leaves behind at your Dr and hospital.
The Medicare Advantage Plans disenroll you from A&B and puts you with a private network of Dr and Hospitals and now you will pay as go with copays and deductibles.
Of course there are many other differences.
Can anyone name some?
