How they differ
Medicare Advantage (Part C) replaces Original Medicare with a private plan that bundles hospital, medical and usually drug cover, works through a network, and caps what you can spend in a year. Plan G is a Medicare Supplement: you keep Original Medicare, see any provider that accepts it nationwide, and the policy pays almost everything Original Medicare leaves behind except the Part B deductible.
The trade is predictable: Advantage plans usually cost less each month and more at the point of care; Plan G costs more each month and very little when you actually use it, but needs a separate Part D plan for prescriptions.
Which suits whom
Travel, a preferred specialist outside the local network, or a strong preference for predictable bills tend to favour Plan G. A tight monthly budget, satisfaction with local in-network doctors, and interest in extras like dental or fitness tend to favour Advantage.
