httpinvoke and superagent differences:

* superagent has a "fluent" API, httpinvoke is a plain function, with an options object and with Node.js callbacks and/or promises.

* superagent is not easy to use with binary uploads/downloads

* superagent does not give you an abstraction over progress events

* httpinvoke does not build query strings

* httpinvoke gives you raw multipart/form-data responses, does not parse them

Other aspects are comparable (file size, Node.js and browser support, etc).
