I had a 03 expedition and it had numerous problems. I traded for the Beast about one year ago. I am very happy I did, the beast is fun to drive and pulls a 7800# boat much better. Over all I feel it is a better vehicle.
Four wheel drive system, engine power, styling, Bose system, tow capacity, self leveling system, curtain air baggs for all three rows. Tire monitoring system.
The interior materials are not as damage resistant as the expedition, also the seats are less comfortable. Add lights to the stearing wheel controlls and lights that would come on when the doors are unlocked. The doors do not lock when put in gear. The third seat needs to be split.
