Couldn't have said it better myself.
But to clarify... BMW OE is about "good" handling and "good" comfort, whereas aftermarket can be adjusted to be "good" handling and "great" comfort, "great" handling and "fair" comfort, or any combination thereof... BMW aims for the baseline of what consumers will want, and hits it right on the mark.
Now, if you buy a 997 GT3 RS... OEM is going to be roughly as good at handling as any aftermarket setup (well, almost...) because Porsche designs it for a specific purpose
Your 3 series wasn't designed for the track. But you can fix that
