RC:

Comparing McLaren cars with the 911 Turbo S is not really possible since the Porsche is basically the best daily driver super sportscar on this planet, there is no doubt about it. 

This is correct. And yet, my above summary focuses on driving pleasure only. Even in this category Porsche seems very competitive to me Smiley

The major disadvantage of the turbo s is the lack of some other 50-100hp to compensate for the McLaren's advantage in straight line performance. In all other chapters I see no need for any changes. No kidding.
