We have been using in some of our models and doing design experiments on metal cones since 1985 and have a good depth of knowledge into their characteristics. To sum it up as briefly as possible, the main advantage is the cone rigidity, which stops the cone itself from distorting especially at higher output levels. The disadvantage can be resonance if the characteristics of the cone are not designed properly. We know how to do it properly and avoid any of the resonance issues. This means you can have smoothness and accuracy at all volume levels.
