I have the 3.0 with SP and I LOVE it. I don't feel that the ride is too harsh at all. In fact, other people that have ridden in the car agree that it feels great. I would strongly recommend the Sport Package on the 3.0L. (I didn't drive the 4.4L with SP, so I can't comment on how the 19in tires would feel). Good luck...you'll love the vehicle.
