I would say go two post, gives you so much more room to work under the car vs the drive on. If you are lazy, the drive on is great. The two post allows for easy wheel removal for brakes, steering, suspension, bearings, etc. plus nearly unrestricted access to the underside for exhaust and major driveline components. You can still easily store a car under it, my buddy's shop has a 2 and a 4 and stores cars under both.
