The actual answer to "which is better"

Neither carrier is universally better. The right Medicare plan depends on three things: your doctors (must be in-network), your prescriptions (must be on the formulary at a manageable tier), and your total annual cost (premium + deductible + copays + max out-of-pocket). A licensed SilverEdge advisor compares both carriers — plus the 40+ other carriers in your county — on those three things in 15 minutes. Free.
