Have used both and will always use arrival service. If we arrive and it wasn't needed so be it but I have spent hours trying to get out of the airport. $80 for two to get to Negril and hour or so earlier is well worth it to us. We have used departure service a few times and don't know if we will next time or not. MoBay has a great airport and I have no problem spending an hour or two shopping and eating in the terminal. The departure line doesn't bother me much since I am already depressed about going home. If you want to drink a lot before departure the club may be worth it for you. The snacks are ok but I saw many people ordering in real food from the terminal restaurants. Arrival service is my new favorite.
