Off road, rough: Raptor

Off road, European Rally, I'd have to look at the driver's record. I bet the Raptor would give it a run for it's money with a 6.2. With a 5.4, Porsche.

Snow: Which ever has the better tires, although if you are talking really deep, unplowed snow: Raptor.

IMO, I'd rather have a new Ford with a warranty than a used (and who knows how it was used) turbo Porsche. If I won the lotto, I'd buy new--one of each.
