I found this on the rebates/subsidy ending, Obamacare's 'subsidy cliff' eliminated through 2025IIRC Obama care had some significant premium reimbursements depending on your income. If you're both retired, it might be a good option. But I've also heard that the premium rebates are supposed to end either this year, or sometime soon.
Who really knows if it will end.
What is scary/interesting, is the price comparison in the link with and without the subsidy. Basically, without the subsidy, the premium payment in one example, though a different state, was about what I and my employer are paying for health care coverage. The cost is more than we pay for a mortgage, house insurance and property tax....
