I really like the chrome KGO with the tank on it. It's no different operationally, or quality wise than the black KGO with the tank on it--it just looks nicer (IMO). I think I like it better because the adapter (the fitting that hides the neck and connection between battery and tank) only comes in chrome, and kind of stands out on the other KGO colors. On the Chrome colored KGO it becomes part of the unit. They need to make a black (or gold since the black KGO has gold accents) tank adapters too.
