Absolutely choose Cigna. PPOs are worth it.
Saying that, FCPS screwed employees with the sub-par service that is Cigna. We used to have BCBS (which was great) and then Aetna (which was acceptable).
My doctor's network (Privia) almost left Cigna 2 years ago, but they didn't.
FCPS has a crappy plan where you have to pay a lot, which didn't use to be the case. But there it is.
