 Mercedes had a service campaign (silent recall) on their drilled rotors for cracking soon after they came out.
Newest ones are made differently, similar cast-perforated (not drilled) as I described above.
They use them because that's what customers ask for. No performance gain. Customers ask for purple paint, too, and any auto maker is happy to oblige to make a sale.
