The advantage of a drywall ceiling in a basement is that the room in the basement looks more like a room that is not in a basement. If you drywall the ceiling you can bet that there will be a water leak above and you will have to fix the damage. If you install grid work and ceiling tiles it is easy to replace the ceiling tile if needed and you have access to your mechanicals. So you need to decide if the occasional repair is worth the drywall look. I go drywall with a few access panels, if you feel you need a lot of access panels it will affect the appearance and then you may want to do the suspended ceiling. Good Luck
