IMHO you should look for features that are important to you. For example, my wife likes having her own volume controls for radio, intercom, and music. And they have to be easy to use (if it involves 3 button pushes we'll both soon forget the procedure). Also, consider if you really need an audio panel, or just a good intercom. These days there is less switching than there used to be, with flip-flop radios, no ADF, no MB, etc.
