Get Glorify if you want something that can do double duty as a bronzer. WoG will be the most neutral one, if you only want sheen without any change to your skin color. Superb will give you a hint of color along with the incredible sheen, but just enough to enhance, rather than transform, like Glorify does.
If you already have Crystal Pink and Pearl from Semi-Precious, and even Goldstone, you might want to pick Glorify, if you're not afraid of bronzing if you use it all over. It's most different to the Semi-Precious MSFs, color-wise. If bronzer isn't your thing, the choice is between if you want the option of some color (Superb) or no color, just sheen (WoG). Hope that helps!
