Sounds like it doesn't.
If you use it with like a 3PJS or 3PK (with HRS reciver) it will make better laptimes if you are good enough. In generall, digital servos are more precise and centers better. It feels like they have better torq also due to the fact that they work more and faster - they call it better holding torque. If you turn on the radio with your existing servo and carefully try and move the servo arm you'll notice you can move it a few degrees before you really feel it starts to work. With like a S9550 you cant do that, it starts to fight instantly. Thats the main reason they draw more amp - they simply work more often (at a higher frequency). Basically I'm talking of Futaba, cant talk of other brands... ;-)
Preferably use same brand as the rest of the system also.
