While I'd rather have the new Mercedes than the BMW or Audi, I'd rather have the Porsche than the new Mercedes. Mercedes has basically tried to make a Porsche 911 here, and while the exterior is pretty, the interior is gaudy and awful, and the packaging in general is still less clever than the Porsche.
But I'd also rather have the old Mercedes than the new Mercedes, precisely because it is what it is, a Viper-like battleship of a sports car.
But I'd also rather have an actual Viper than a Viper-like Mercedes, because I'm a man and I take my punishment as it comes.
