I guess that would depend on what type of activites you enjoy on board ship. Some of the party stuff starts after first seating and will be going on while you sit at dinner in the late sitting. If you go on an excursion and dinner is early then you have to hurry up to get dressed for dinner right away. If thats ok with you then go for that.
I preferred to relax before getting ready for dinner so we chose late seating.
Life is too short to let the ship of your dreams sail without you.
