Basement Renovation

We are in the process of finishing our basement, and am torn between whether to dry wall the ceilings or use drop ceiling tiles. Our ceiling is low already, and I want to drywall; however, my husband really thinks drop ceilings are the way to go because of easy access to wiring, plumbing, etc. We've never had anything go wrong down there yet in the ceiling (9 years), and just how much of a hassle could it be to cut a hole and repair and replace drywall.
