How can I explain team feign is good choice for REST client?

[hellboy81]

Which advantages brings Feign compared with JAX-RS Client, OkHttp, UniRest, Retrofit, Akka HTTP Client and another?

Well, a feign client will look like you are talking with a good api.
Also, you can easily mock.

In general, at work, we inject clients on constructors, so, when I'm unit testing my classes, I can easily use mockito to create the client.

One more thing, readability

interface GitHub {
  @RequestLine("GET /repos/{owner}/{repo}/contributors")
  List<Contributor> contributors(@Param("owner") String owner, @Param("repo") String repo);
}

much easier to read than

  returnedEvents = client.target(baseUri)
                    .path("all")
                    .request(MediaType.APPLICATION_XML)
                    .get(new GenericType<List<Event>>() {
            });

Would be great to see responses to become a PR to improve this section

May be code quality index can help:

• L4 vs L2
• L4 vs L1 ?

Which lib has also L4 index?

I agree with @velo on this and #955. Could we either update the area on the readme with more information or provide a Wiki page with this information? Would you @hellboy81 or any other member be interested in providing that information?
