Me too.
I think the FERS 1.1% per year of service pension is underrated. Of course that depends on your potential time in service. I'll have over 20 at the end, so that adds up. No one gives pensions anymore.
Active duty and DOD federal employment are very different. I'm guessing the things you didn't like about the Navy are the usual things- long hours, working conditions, forced separation from family, arbitrary rules (and forced compliance). Civilians are treated better, with normal hours, overtime pay, lots of holidays, safe work environments (OSHA), So one person mentioned Furlough, and I'll have say that does suck. Just the arbitrary nature of the possibility. It depends a lot on having an approved federal budget, and if you pay any attention to politics you know that isn't easy. So no matter what you do, what your boss does (or they're boss, or Sec Def, or President), the specter of it can linger. Absolutely the antithesis of the security I took this job for. That said, in my 15 years furloughs were implemented twice and both times some things / departments were still funded or partially funded. So I actually was "furloughed" once for like 3 days before I was called back and we were excepted from jump the other time. And in both cases pay was restored in full to those who got the temporary cut.
