Of course there are differences between Health Sharing and Insurance. All those laws and regulations (and bureaucrats) that come with traditional health insurance come with a very steep cost - and even then there is no gurantee that the insurance company is going to cover your costs.
What I can tell you about health sharing is this: Our family went with Sedera in May of 2021. In early July 2021, I had a mountain bike accident and broke three ribs and punctured a lung. We had elected to have a $2,500 out of pocket "deductible." We paid this, and Sedera covered the rest (another $25K +/-), and it was simple and no hassel. And we pay about $600/mo. for our family of three.
Navigating health care coverage is scary stuff, no doubt. I clearly remember being in the ER thinking, "welp, here goes. We are going to find out real quick if this works. . . " Compared to our old BC/BS plan, Sedera was easy, helpful, responsive and ethical. And we don't have to worry about being in this state or that provider network - it works the same everywhere.
YMMV.
Good luck to everyone.
