Moonshine is a cleaner/polisher while Energizer is only a cleaner. If you want to keep a particle ball clean and shiny, Moonshine would be one way to do it. I haven't used it, though, and as far as I know, most Storm balls are factory finished with their Step 1 and 2 compound polishes if they're polished at all.
I've used Energizer by hand and I didn't really care for it. It left the ball feeling slimy, greasy, and I couldn't get that stuff off with a wet or dry cloth. Maybe on a spinner it would be different.
My favorite cleaner is Track (nee Powerhouse) Clean & Dull.
