1. Data Organization: Redux Dynamic Modules allows for dynamic loading and unloading of modules at runtime, providing flexibility in the organization of data and logic in a Redux store. Redux.js, on the other hand, follows a more traditional approach of static module loading during application initialization.

2. Abstraction Level: Redux Dynamic Modules abstracts away the complexity of module initialization and management by providing a simpler API for dynamic module creation and configuration. In contrast, Redux.js requires manual setup and configuration of modules, which can potentially lead to more boilerplate code.

3. Performance Optimization: Redux.js with Reselect offers built-in memoization through selectors that can help optimize the rendering performance of React components by preventing unnecessary re-renders. Redux Dynamic Modules does not explicitly provide this level of memoization out of the box, requiring developers to implement their own memoization techniques if needed.

4. Code Splitting: Redux Dynamic Modules supports code splitting and lazy loading of modules, enabling a more efficient loading strategy for larger applications. Redux.js, while compatible with code splitting techniques, may require additional setup and tooling to achieve efficient code splitting capabilities.

5. Maintenance and Scalability: Redux Dynamic Modules can contribute to a more maintainable and scalable codebase by allowing the addition and removal of modules on the fly, facilitating easier code maintenance and updates. Redux.js may require more upfront planning and structuring to ensure a scalable architecture, especially as the application grows in complexity.

6. Community Support: Redux.js with Reselect has a larger and more established community compared to Redux Dynamic Modules, which means more resources, plugins, and support available for developers using Redux.js. While Redux Dynamic Modules has a growing community, it may have fewer resources and community-driven enhancements compared to Redux.js.

In Summary, Redux Dynamic Modules and Redux.js with Reselect offer unique approaches to managing state in a React application, with differences in data organization, abstraction level, performance optimization, code splitting, maintenance, and community support.
