Choose Traditional Medicare If:
You value absolute freedom to choose your doctors, travel frequently within the United States, and want to avoid dealing with insurance company pre-approvals for care. (Many people pair this with MediGap/Medicare Supplement policies to cap their out-of-pocket costs.)
Choose a Medicare Advantage Plan If:
You prefer a lower upfront monthly premium, want all your medical and drug benefits bundled into one plan, and value extra perks like routine dental and vision coverage... AND PLAN TO REMAIN HEALTHY.
