I'd be interested to see a good in-depth analysis. If you get a vanilla annuity, you have significant inflation risk over decades. The guys who bought annuities in e.g. late 60s saw them destroyed by inflation. It's not a great fit for a 30-year retirement.
You should be able to get an inflation-adjusted annuity at the TIPS rate plus a credit spread. But right now that TIPS rate is effectively nothing. And I don't know whether the credit spread plus the insurance company tax benefit is a good deal.
Packaging e.g. an S&P index fund in an insurance product, so you don't pay taxes until you get payouts, would be a really good idea, but typically insurance companies tack on sales commissions and fees far in excess of e.g. SPY or VFINX. If Fidelity or Vanguard offered that, it would be a good deal, but I hadn't seen that... looking at that Fidelity product now https://www.fidelity.com/annuities/FPRA-variable-annuity/ove...
