I'm sorry honzakoubek, but you can't say a priori that Porsche is faster than Ferrari, always. Like me, I can't say the opposite.
The generation that originated from the 458 Italia is a project that after ten years of development, on that chassis, still generates fantastic machines, such as the 458 Speciale, the 488 Gtb and then 488 Pista.
Porsche 918, LaFerrari and P1 are three hypercars with more or less aligned times, depending on the circuit.
Ferrari has worked and is working very well, for ten years now, refined and very performing projects.
I also have a lot of respect for Porsche, but I don't feel like making certain claims.
