Class-based views are a great way to keep your code DRY and make it easy to reuse. They allow you to create reusable views that can be used in multiple places in your project, so you don't have to repeat yourself.
Class-based views also help keep your classes small and focused. When you use a class-based view, each part of the view is kept in its own class that has only one responsibility: displaying data. This means that if something changes in one part of the view (like its template), it won't affect other parts of the view.
Finally, class-based views are great if you want more flexibility when working with data because they allow you to pass different pieces of information into them based on what's needed for each individual piece of data displayed on the screen at any given time.
