No doubt Potentiometers are cheaper but trying to use one on our kicker for Breakaway we found they can not handle a high rate of acceleration. One release of the surgi-tube powered kicker from fully retracted was all it took to break them. We had to switch to an encoder and then add a limit switch to sense a point to start watching the encoder counts from.
