If you want my .02, and I am biased, the new 4.8 looks awesome! I have never driven it but I would only imagine its head and shoulders above my '02 4.6. I don't like the the Pepper facelift or not (true Porsche fans don't like anything except the 911) and the 4.8 will run circles around the Rover sport and has more cockpit room and a 3rd row. When I sat in the Rover Sport I felt like I was sitting in my wife's Toyota Highlander (a little tight for me).
