M6 Competition Gran Coupe / tyre recommendation

Hello Community, for my BMW M6 Competition (305 km/h peak) I need tyres with the following dimensions: Front axle: 265/35ZR20 99Y Rear axle: 295/30ZR20 101Y Currently Pirelli P Zero tyres are installed. Now I swung between “Pirelli P Zero (PZ4?)” and “Michelin Pilot Sport 4S (LS?)”.Which one can recommend? Other suggestions are of course welcome.Wish to select tyres that offer as high a traction as possible, whether the Pirellis can do everything in this discipline. I would, however, like to doubt it as a non-connoisseur.
