Congrats on your achievement! I think either choice is fine, so pick the one that is most comfortable, partly because stress can shorten your life.
Full-time work was very uncomfortable for me, so I quit while still shy of my savings goal. I just reached the goal, two years after retiring, because we had learned how to live within our means and the market has been good. (O happy day!)
Now that we have enough money to support a good monthly draw, we will adjust spending to protect the amount of savings we want to maintain. If you like your job and want more of a financial cushion, working a few more months seems prudent.
