The benefit of traction control removal is that you get to buy new tires more often and when you need to make a grand exit, you can do so with an abundance of tire smoke. Aside from that, the chief benefit is that you don't have to worry about power being reduced under conditions of light tire spin. Rather than complete removal, it's usually better (depends on the vehicle/operating condition combination) to reduce the aggressiveness of the settings. If you play with it enough, you can get to the point where you just haze the tires during full throttle accels. That frequently leads to better and more consistent 60-foot times than can be achieved with an educated right foot.
