- **Size of Serialized Data:** Java serialization tends to produce larger serialized objects because it includes class metadata and other overhead.

- **Flexibility and Control:** Java serialization offers limited control over the serialization process, such as excluding certain fields, customizing naming conventions, and handling complex data structures more gracefully.
