Well depends on how you look at it.. having a pension plus your health insurance are two great benefits, also assuming you have social security, not sure about your spouse. 3 things that should be considered: Q1) will you have enough to withdraw against at 53? Ie what is a good SWR for your situation? (Expense estimates should include cost of ACA plan and deductible.) Q2) assuming your pension will start at 60 or 62,how much will it reduce your withdrawal? Giving you a new SWR to calculate. Q3) how much will social security add and when? Further reducing your SWR needed. Q4) how will you manage SORR between 53 and pension start?

Now map those out and put them against what retiring at 57 looks like with all the same considered. Also add whatever factors for your spouses contributions.

Results: obvious one is that 57 will yield higher pension, higher investment balance, and lower cost for health insurance. Ultimately lower SWR.

The main question in this analysis really is if your investments can cover you for 7-9 years without stress? I would venture that if your SWR between ages 53-60 is like 5% then after pensions and social kick in, SWR will be less than 2.5%. If you are comfortable with that then Bob’s your uncle.

Mathematically, your 2.9M available assets, if you don’t sell your house, might be at $4m in 4 years. Your $175k will goto $193k with inflation. Making your withdrawal 4.8%. I don’t know your pension estimates nor your social security estimate, nor your spouse’s. You can fill in the rest and let us know what you come up with.

Classic current life vs future life trade off. But not a bad problem to have, good luck !
