The 660 was bench marked to perform at the RE71 level and wear better. It really is up to what you want out of a tire.
Just getting started and care more about turning laps than being fast and street drive alot: Hankook, Nitto
Intermediate who wants to set the fast time with your buddies but will sacrifice wear in HPDE: RT660, RE71R, Rival S
Chasing a lap time instead with a large tire budget for the year: Yokohama
