Here's a paste from Meguiar's forum. It's a confusing study, but at least it shows the relative properties. Most are SMAT Technology, which I always understood to keep a constant grit throughout the process. Some forum posts, even by the mods, occasionally refute this.
Aggressiveness Order for New Consumer Products - This will surprise you! :shrug:
Since we introduced these 3 new swirl and scratch removers in our Consumer Line and our new M205 Ultra Finishing Polish in our Professional line, many people have asked how aggressive these new products are as compared to some of our existing products that our forum members are already familiar with to help them understand the cleaning and/or abrading ability of these new products I've listed them in order of most aggressive to least aggressive reading from left to right.
(Apologies ahead of time if you have to horizontal scroll)
Most aggressive to least aggressive -->
That would be from most to least aggressive,
