The latest version of the Continentals, ExtremeContact Sport 02, test up favourably against the Michelin Pilot 4 S and in many sizes can be $60 to $100 less per tire. I have a set of them ready to go on my 12 GT500, squaring up the size to 285/35R19 all around on some aftermarket wheels.
It comes down to what you want to prioritize, all around performance and decent street manners, or emphasis on straight line traction.
