Not sure how much help, but as a federal employee, I've always had BCBS Basic (the cheaper option). Most of my co-workers use BCBS, the only exception is one guy who chose GEHA, because he could choose any doctor (in or out of network, I guess the benefits are the same? I don't know), specifically because his wife's family has a history of breast cancer. This guy wanted the option to pick any oncologist he wanted, and not settle (for example) any doctor in-network.
The only other coverage I had was Foreign Service Benefit, and that was when we moved overseas with my job (easier claims, although I hear BCBS offers similar services).
Every year, I consider a HDHP, but until I have the deductible limit saved ($5k), I'm leery (clumsy kids, etc.).
