No 401k can ever match the beauty that is the TSP.
Oh that's actually really good. Beats a TSP for sure even with the fees. But from what I remember you're at a defense contractor - they probably have the best benefits plans overall in the US.
That’s by far the best I’ve ever heard of. Usually employers screw us by keeping the majority of the max annual contribution, which only they can make, out of our reach with crappy “50% match up to 3%” policies or whatever (even a 100% match means you can’t hit the actual annual max, it has to be higher than that).
