when you look at the specs for speed anything slower than 0.1 secs is gonna be a disadvantage, speed is what determines reaction time. the intial response this helps the car turn faster and also the wheels will center itself faster. (think about powersteering and a non-power steering car)
For torque 6kg and above is ideal for electric cars. torque helps the wheels stay in the direction you want to turn, without torque when your corner the force will be to strong for the wheels to hold the turning angle. so torque is important in steering as well.
for quality and value the futuba s9550 is the best choice.
