I recently ordered a few bottles (3,1 and 0.5 microns of Gunny Juice storpping material). They are water-based poly diamond compounds. For the last 3 years, I have been using a 4-micron Jende CBN compound and the results are amazing. I have used several cheaper diamond compounds, both oil and water-based ones and they are much inferior to the Jende CBN compound (also they are much cheaper).
I believe there are three major factors affecting the quality (and end results) of a compound. The abbresive concentration, uniformity of abbressive sizes and the amount clogging in the compound. In some cases (according to Gunny Juice marketing guys) the abbresives can get clogged in the carrying medium (oil or water) and they become much larger than intendent sizes. For instance, several 1micron particles can clogged and create an abbrasive piece with a size of several micron. Obviously, this is not something a sharpen would want as it will cause irregular scratch pattern and possibly reduction in sharpness. The biggest selling points of Gunny Juice (again according to their marketing team) is uniformity of the abrasive sizes in the compound and the technoogy they are using to prevent abbresives from getting clogged.
Below are the pictures of the results I got using the Gunny Juice compounds.
This is the edge after Jende 4 micron. Notice the relatively large scratches at some locations along the edge.
After 3 micron Gunny Juice. Notice the how those relatively large scratches disaapeared after 3 micron Gunny Juice eventhough there is not much difference in size between 4 and 3 microns.
And the final picture is showing the edge following 1 micron and 0.5 micron Gunny Juice progression.
