Ferrari: anything goes. Outrageous is expected and appreciated by almost everyone. I've never seen a ferrari which I didn't love on first sight. Even the turquoise interiors with bizzare paint-to-sample make me happy when I see them.
OTOH:
DS invariably makes me wonder, "What's the point?"
Porsche deviated stitching is like getting a tattoo on your face. It's what everybody sees first and takes a long time for your friends to get used to.
Just because Porsche offers it as an option doesn't mean it looks good.
All of this is In-My-Most-Humble-Opinion of course.
