The vex line followers work on a different concept the the KOP sensors. The supplied sensors are your basic yes/no, is it, or is it not on the line. Vex sensors measure the intensity of infared light that reflects off of the surface being measured; the vex sensors return integer values based on the intensity, there's a data sheet that comes with them that explains it more in depth. The major difference in using them would be using the analog breakout rather than the digital sidecar along with using comparisons and then going to a true/false case structure, rather than going directly to a true/false case structure, in programming.
