There is not true or false here, one media is good for something while other is better on other part.
Most commonly used media in old times, which is stilll being used, just a lot less, is sand. Different sized grains of sand made different effect on surface. Nowadays sand is not used that much any more. Reasons are obvious, sand producec way to much dust which covert all the area where we work and is also hazardous to our health.
