For all of the reasons mentioned above with low turn brushed modified motors the belt driven car is a bit softer and easier to drive as were and doesn't suffer from torque steer. Remember most (all) TC kits are designed to compete at the highest level not just club or regional events so if the trend was to all go belt then so it was.
Although a well balanced car something that wasn't a common thing to do back when shaft was popular would of helped a great deal with torque steer, also brushless motors do help alot as there is less rotating mass compared to the brushed motor.
