Traction control will apply the rear brakes in pulses like antilock and/or reduce power thru fuel or spark. Whereas a moderate amount of wheel spin will keep your revs closer to peak power. Too much wheel spin can make for a bad launch
and no wheel spin can cause bogging. It all boils down to how your car is set up,
I.E. how much power you are putting to the ground and wether or not your suspension can transfer weight to the rear tires, and that those tires offer enough grip to launch without bogging or spinning excessively.
