I think the best looking exterior is the M sport.

That said, overall, i like the x-line. The wheels are cooler than the sport line imo. And you get some additional side/under protection with the aluminum skirt (though it's mostly for looks).

Sport interior: The bigger deal is that while you do get the sport seats, the color options are horrible for the regular sport line. Unless you like black. But i've always felt like i were in a cave with a black interior. Lighter interiors make the car feel much bigger inside, but then again, you gotta keep it clean. So it's a trade off. Though you won't have that problem with your x-line interior selection.

For me, all things being equal, it came down to what's more important, exterior or interior? I care more about what i see, where i spend more time, than what someone else sees. So interior matters more. That's kinda how i made my decision.

Whatever you choose it'll be sweet! Good luck!
