TrinaLC now knowing that you are flying from NYC, I would make a decision based on schedule and convenience and not on food and beverage. I fly from LAX to Paris and the flight is about twice as long, thus, there is more to consider (including, serious jet-lag). Both, AF and DL will do a comparable job in Y. Check the schedules and see what works best for you.
Good luck. Both AF and DL are great choices.
