What is the best abrasive media to use?

I've been useing crushed glass.
There is a local company that buys up all the recycled glass in the area and refines it.

They are a supplier too Eastwood but Eastwood breaks down the 50# bags and relabels it as their own and sells a jug for many times the amount of a bag.

A 50# bag cost me $6.00 at the door.

The problem comes where the company has changed names at least 4 times since I've been going there. And it's been over a yr. Since I've been there but the last name they went by was LVI industries.

Recycled glass cuts ok but it does break down quickly.
for the price I can't complain.
