As most have said, it depends upon what the motor is used for. One of the problems is that they are called trolling motors when in fact not many people use them for trolling. They're ok for trolling with a canoe or small tinny. Larger boats troll using the main motor or, if it's too fast, they'll use a kicker motor. Bowmount electrics are almost all used for positioning. I've owned RF motors and pedal cable steers. I presently use the cable steer and it works well. If I was to buy another I'd probably go with a transom motor mounted on the bow. They are much more reliable, much cheaper and all that's needed is to turn the head 180 degrees for forward running. It is much easier to steer with a tap of the hand or knee to go in the direction you want than to steer using a gas pedal type arrangement. Steering is done instinctively with your hand and it is direct.
It really depends on how you use an electric.
