They are alle resistors, doing essentially the same, but they differ in the material they are made of.
Ceramic is a common and cheap one. Polypropylen is another material as would "oil and paper" be in old-fashioned ones.
Some guitar players claim that some of these "sound" better with the tone pot. I cannot verify nor deny it, as I never used other material (as I wrote above the polypropylen ones didn't work as they were a wrong rating). However, I figure if you only very seldomly use your tone pot there isn't any difference to worry about.
