With respect, even hard anodizing is simply for aesthetics and it doesn't have the mohs hardness to withstand the abuse of metal on metal contact. In a high stress environment like a chain/sprocket interface, it won't remain on the teeth for long.
To give everyone an example, hard anodized on the chainrings of a well maintained bicycle won't even last under the torque of a human being with a fraction of a single horsepower. On aluminum motorcycle sprockets it's gone very quickly. Still, it's good for keeping the non-contact areas of the aluminum from experiencing unsightly surface corrosion so it has some benefit.
Go steel. Unfortunately most steel sprockets look pretty dull except for the Driven Superlite steel sprockets. They're pretty trick.
