Swing in Java GUI programming is highly significant due to its rich set of widgets and advanced features. It is a part of Java Foundation Classes (JFC), which is designed for creating desktop applications.

Key Features of Swing:

1. Lightweight: Unlike AWT, Swing components are lightweight because they do not use the native system's resources.

2. Rich Controls: Swing provides a rich set of advanced controls like Tree, TabbedPane, slider, colorpicker, and table controls.

3. Highly Customizable: Swing controls are highly customizable. One can easily change the look (L&F) of the controls.

4. MVC Architecture: Swing follows the Model-View-Controller architecture.

5. Pluggable Look and Feel: Swing supports the pluggable look and feel, which means that we can change the look and feel of the application.

Swing vs AWT:

1. AWT components are heavy-weight, whereas Swing components are lightweight.

2. AWT components use the system resources, i.e., they are platform-dependent. But, Swing components are not system resource dependent, i.e., they are platform-independent.

3. AWT does not support pluggable look and feel, whereas Swing supports pluggable look and feel.

4. AWT provides less components than Swing.

5. AWT doesn't follows MVC (Model View Controller) where as Swing follows MVC.

Examples of situations where Swing would be preferred over AWT:

1. When you need a customizable and flexible UI, Swing is a better choice because of its lightweight design and pluggable look and feel.

2. If you are developing an application that requires a rich set of controls, like trees, tables, or tabs, Swing would be the preferred choice.

3. If you are developing an application that needs to be platform-independent, Swing would be a better choice because it does not rely on the system's resources.
