There is not a "best" tire.
There are many factors to consider when purchasing a performance tire. Some are, how heavy is the car, fwd/rwd/awd, hp of the car, type of driving, type of roads, road temperature, ambient temperature, et.c All of thes (and musch more) affect the decision of what compund and construction to use. In the end, it's all about getting a tire that is predictable. If you know exactly what the tire will do/when it will let go, you will have more confidence, and thus, will go faster.
Example: For my old 85 RX7, I had a track wet weight of 2560, and w/o the N20, rwhp was usually left at 156. Car was rwd, with an almost exact 50/50 ration. I ran 1.5 degrees, and car was mainly run in varying conditions (some wet/some dry), but always in warmer climates (no real winter conditions). After testing several tires and evaluating, I found that the Bridgestone S03's were the most predictable tire for me. I managed to put better lap times on those than any other street tire.
Converesly, these tires might or might not be the best choice for you and your car. You might feel more comfortable with Hankooks, Falkens, etc....
