Just like with pastels - there are different grades of enchi's. A low grade enchi will look very similar to a banded normal.
I'm hoping that enchi's don't go the way of pastels, being pumped out for the sake of keeping up with the demand with no regard to quality. As you can see from the pictures I posted before this one, that was a top of the line quality enchi, and there's no mistaking it for a normal.
