...electric brakes are much better/smoother and can be acctuated manually from inside the car without acctuating the car brakes, they can also be fine tuned from inside the car to suit driving situations(wet/snow/icy roads)
...hydraulic or surge brakes are OK in an emergency situation but are not very smooth or acurate otherwise and can actuate themselves when not wanted such as going up/down a hill, shifting/accelerating
...the newer electric controllers do not tap into your brake line. Some of them hook up to the brake light curcuit and the better ones use an accelerometer chip and hook up to nothing but a power lead and the trailer brakes themselves...if I had my druthers, I would definitely go with electric brakes
