My RS3's work quite well. Take all the abuse I throw at them. Decent road noise for a 245 "street" tire.
Mind you, you have to ask yourself whether you are actually able to get 100% of the grip out of the tire (alignment but, mainly driver. Are you supplementing tire grip for driving ability?). I'd say, most of us, myself included won't be able to come within the limits of the tire. So why not save some of the money and put it towards track days?
If, you want to split hairs and talk about theoretical "best tire" the RE71R's are your tire of choice (this year).
Hopefully I don't start a flame war. Haha
