1. Clear, and concise interface for the 'entire' http request lifecycle.
2. Lots of compatibility and support for various protocols, headers, request bodies, etc.
3. Good team sharing ability if you use the paid version.
4. The test runner, and the environment variable hosting is HUGE time saver. Review collected by and hosted on G2.com.
The test runner, while incredibly powerful, has some features in it (like saving variable output from one request, etc.) that are not obvious, and feel a little hacky to implement. Review collected by and hosted on G2.com.
