The only way that I can see how a round front is "better" than a pointy front are the other non-aerodynamic reasons for having a short overhang.
Those pictures Piwoslaw posted very clearly show better airflow under the nose. The pink stream quickly reattaches, and stays attached the entire length of the underside, while the pink line under the semi round front is destroyed and never reforms.
I would also bet that barometers placed at the nose would show better, lower readings in front of a pointy nose.
I am also inclined not to think that the engineers of Porsche, Ferrari, McClaren, Mercedes, Audi, etc. are completely clueless.
