The annuity has some advantages such as guaranteed monthly income for life but before you go that route please remember the payout is totally fixed (not like SS which is indexed for inflation so it preserves purchasing power) and inflation will slowly erode your purchasing power.
Even with a low 2% annual inflation rate, your purchasing power in real terms will be only 80% of the amount that you started with when you retired after 10 years. A couple of years of 5%+ inflation and the result is much worse.
No right or wrong answer between lump sum and annuity just think hard and long regarding both options.
