This is the question that keeps me busiest every fall, and honestly, it’s the right question to be asking. There isn’t a universally correct answer here. There’s only the answer that fits your health, your budget, and how you like to live. Let me walk you through how I think about it, the same way I would sitting across the table from you.
They solve two different problems
Original Medicare, which is Part A and Part B, is run by the federal government. It covers a lot, but it leaves gaps, and it has no cap on what you could pay out of pocket in a bad year. Medigap is a supplemental policy from a private insurer that fills in those gaps, things like your coinsurance and deductibles. Medicare Advantage is a different animal entirely. It’s a private plan that bundles your Part A and Part B coverage, usually your drug coverage too, into one plan with its own network and its own rules. You cannot use a Medigap policy alongside a Medicare Advantage plan. You pick one path or the other, as U.S. News lays out clearly in their side by side breakdown. Medicare’s own plan comparison tool is worth bookmarking too, since it lets you look up the actual Medicare Advantage plans and Part D drug plans available in your specific zip code rather than relying on national averages.

What it actually costs you
Here’s where I see people get surprised. Most Medicare Advantage plans still charge $0 for the plan itself, but you’re still responsible for your Part B premium either way, which is $202.90 a month in 2026. Medicare Advantage plans do have an out of pocket cap, set at $9,250 for 2026, but you’ll pay copays and coinsurance along the way to get there. Original Medicare paired with a solid Medigap plan runs higher month to month, often $200 to $280 depending on the plan and your state, but once you’re in it, a bad health year rarely costs you much more. I usually explain it this way. Medicare Advantage saves you money when you’re healthy. Medigap protects you when you’re not.

The doctor question
If seeing any doctor who accepts Medicare, anywhere in the country, without a referral matters to you, that leans toward Original Medicare plus Medigap. If you’re comfortable with a network and you want extras like dental, vision, and hearing bundled in, Medicare Advantage tends to be the better fit. Nearly all Medicare Advantage plans now include some level of dental, vision, or hearing benefit, but the coverage varies a lot from plan to plan, so read the actual benefit summary and not just the brochure.

Timing matters more than people realize
If you sign up for Original Medicare and a Medigap policy the moment you’re first eligible, insurers can’t turn you down or charge you more because of a health condition. Wait past that window, and in most states an insurer is allowed to underwrite you, which can mean a higher premium or an outright denial if you have something like diabetes or a heart condition on your record. Medicare.gov spells out exactly when this window opens and what guaranteed issue rights protect you afterward. This is one of the more overlooked details in Medicare planning, and it’s exactly the kind of thing that gets missed when people try to figure this out alone from a mailer.

My honest take
If you have ongoing health conditions, see specialists regularly, or simply sleep better knowing your costs are predictable, I lean people toward Medigap. If you’re generally healthy, want to keep your monthly premium low, and like the idea of built in dental and vision coverage, Medicare Advantage often makes more sense. Neither one is the “wrong” choice. The wrong choice is picking blind.
