For my MR2, it was all about the user community. Recommendations varied, depending on what one wanted from their tires, but the now-discontinued Falken Azenis were pretty well-respected for superb grip at a wonderful price point. Of course, they don't last long. Hankook Ventus R also came recommended. From what I hear about the Pilots and other well-recognized "performance tires", they're by no means bad tires, but they aren't the absolute best, and you can certainly find an equally good tire for much cheaper.
