Good as any - you know what you pay and what you get -For Plan N just make sure you see providers that accept assignment or there maybe some higher charges you have to pay (Part B excess charges). You will probably be fine unless providers stop taking Medicare assignment in groves - WHO Knows, not me - I never say never!
Personally it is just GAP insurance so as long as you can afford the premiums for a MediGAP policy of whichever alphabet - you are good to go. Plan N isn’t the Cadillac - but it is fine.
Some beneficiaries just cannot afford MediGAP coveage at all when 1st signing up or even later when premiums rise - thus they have to have other options.
States actually govern a lot about MediGAP plans - so if you are in a state where you can switch at specific times - usually to an equal or lesser plan - you have some options - in most states, you cannot switch without being scrutinized for underwriting.
I would urge you to look at your states dept of insurance for their rules on Medicare supplemental plans.
