Everyone differs here, but I think the X is actually pretty ugly at the front. The hood and grille just seem like a fussy child's face.
I still love the look of the S, and think it's aging pretty well, but I couldn't bring myself to get the X in part because of the exterior design. I ended up with a 2018 XC60.
It wasn't available when I ordered. I had a time constraint, so got the first one off the boat into North America (allegedly), so it has a T6. But all things being equal, I'd love a T8 in there.
