Are large Group Medicare Advantage plans generally superior to individua MA plans?

Since the day I learned that my Medigap Plan G premiums were going up 35% in 2027, I’ve been obsessing about Plan G vs. HD-G and running “the numbers” for best case vs. worse cases scenarios. Somethings been nagging me: While I love obsessing about insurance and wouldn’t mind the paperwork associated with the HD-G. Meanwhile I am eligible for a zero-premium large group Medicare Advantage plan from my former employer, the State of North Carolina. And if I added my wife (with a premium of $68) and predeceased her, she could continue at the spousal rate forever - worry free. What a gift that would be. Reports I’ve gotten from former colleagues suggest that our group plan may be better than individual M.A. plans available to the general public. I would love to hear about your experience.
