Razor,
I don't know a thing about Delta's health care plan, but I'm wondering why you think you need to make a "choice" between the two. Why not use the Tricare basic plan (no cost to you or your family) as your secondary provider, and the Delta plan as your primary. That's what we're doing here at FedEx and between the two, we end up with virtually no medical or pharmaceutical expenses, save the cost of the FedEx health/dental plan, plus the normal deductible at the beginning of the year.
