Dynamics AX 7 Development - Extensions VS Customization

What is the difference between Extensions and Customization and which of them you should choose for your solution?

Model is a unit of development or customization. Extensions get isolated in their assemblies.

AX 7 introduces a new way of customizing an application by using extensions.

Using of extensions allows you to create new model elements and to extend existing model elements.

Using customization you need to create event handlers and new plug-ins.

Advantages of extensions

1. You need to manage only your extension artifacts. 
2. You can service your solutions independently without concerns about other customizations.
