Is there any disadvantage of using ModelVisual3D over Model3DGroup. How much can the resource/performance impact possibly be?

ModelVisual3D gives me much more than Model3DGroup does but AFAIK everything that can be done with Model3DGroup can alos be done with ModelVisual3D.

So why not just always use ModelVisual3D?

Yes. Allthough that artricle describes the difference between the two and alos explains when to not use Model3DGroup it doesn't answer why I shouldn't be using ModelVisual3D.
