1. Execution Flow Control: Chakram allows the ordering of HTTP requests through a built-in control flow mechanism, making it easier to handle asynchronous operations compared to SuperTest.
2. Built-in Matchers: Chakram provides a variety of built-in assertions and matchers for responses, whereas SuperTest requires additional assertion libraries like Chai for response validation.
3. Response Handling: Chakram automatically parses JSON responses, making it more convenient for handling response data, while in SuperTest, response parsing needs to be done manually.
4. Documentation and Support: Chakram has comprehensive documentation and active community support to assist users, whereas SuperTest's documentation might not be as detailed or user-friendly for beginners.
5. Error Handling: Chakram provides detailed error messages and stack traces for better debugging, whereas SuperTest's error messages might be less descriptive and harder to troubleshoot.
6. Request Chaining: Chakram allows chaining of multiple HTTP requests in a single test case for a more streamlined and efficient testing process, a feature that might be more laborious to achieve in SuperTest.

In Summary, Chakram offers easier execution flow control, built-in matchers, automated response parsing, better documentation and support, detailed error handling, and convenient request chaining compared to SuperTest.
