I prefer the factory look.
In my opinion if you pull it and go with nothing you blend in too much with the crowd of family four door fuel economy cars.
If you add something else (almost always it's carbon fiber) you blend in too much with the beater civics/accord/cobolt crew that try to make their family fuel economy cars look fast.
You can't go wrong doing what you want,.... I'm guessing different parts of the country are going to have different views on this...
