From my experience I would say that Rand McNally is better for long trips. I went from Kansas City to Myrtle Beach and my online planner matched exactly as far as road signs and turns. I do admit that I really did not pay that much attention to the actual distance, but the time given was accurate for the speed limit on the roads. I had my wife and 2 kids in the car, so I stayed with the speed limit the entire trip. When I planned it on Mapquest I did not like the absence of finding lodging near the stpping points. The feature on Rand McNally was much better for that.
