Call me crazy but I do both. I mostly use the compass to check if my heading is correct. Then I go to GPS map on the phone to check my location. I still carry a map in some areas but it stays in the pouch.
Edit: Most cellular phones these days have a built in GPS that works off the satellite signals. If you are in an area without cellular coverage, you need to change your settings so your location is GPS only. That will stop your phone from draining battery looking for cell towers or worse - connecting to them intermittently. Getting your phone settings right is critical.
