The typical quadrature encoders used on FRC robotis
are optical sensors. The accuracy is going to be the same, assuming the sensor detects all the marks it's looking for. The precision will be a function of the number of "ticks" per revolution and the consistency of the spacing of the light and dark marks. In general, more marks seen going by in a given time gives better precision.
