Stateless and stateful components in React serve different purposes and are used in different scenarios:

Use stateless components when:

1. The component doesn't need to manage its own state.
2. The component's output is solely based on the props it receives.
3. You want to create simple, reusable UI elements like buttons or display labels.
4. You need to improve performance, as stateless components are generally faster and easier to test.

Use stateful components when:

1. You need to manage and update local state within the component.
2. The component needs to handle user interactions or dynamic data.
3. You require lifecycle methods for tasks like data fetching or resource cleanup.
4. You're dealing with forms or other interactive elements that need to track changing data.

It's important to note that with the introduction of React Hooks, the distinction between stateless and stateful components has become less clear-cut. Functional components can now use hooks like useState and useEffect to manage state and side effects, traditionally the domain of class components.

In general, it's recommended to use stateless components by default and only introduce state when necessary. This approach leads to more maintainable and efficient React applications.
