If you are interested in a comparison between INotifyPropertyChanged and DependencyProperties you can find a good article here.
In general, if the object supports DependencyProperties, try to avoid INotifyPropertyChanged.

No. If you don't intend for your object's properties to change, or you don't mind if the UI doesn't reflect those changes, there's no reason to implement INotifyPropertyChanged.

Further, if your object derives from DependencyObject and its properties are dependency properties, data binding will work without INotifyPropertyChanged.
