I like Pilot Sports
I replaced my stock tires with Michelin Pilot Sports and am very happy. The steering seems way more quicker over the stock Dunlops, and the grip is better. Also if you are like me, and ride rain or shine, most everyone including test articles agree there is not better tire for optimal grip in the wet. I have tried D207's on another bike, and was able to get a little push from them, so I have been a Michelin fan ever since. But, I have heard good things about the new D208's as well.
