title: Styled-component vs jss vs emotion for React
body: <p>I'm trying to understand the best choice (as a CTO) between</p>
  
  <ul>
  <li>jss</li>
  <li>emotion</li>
  <li>styled-component.</li>
  </ul>
  
  <p>I will try not to make the question "too wide" or "off-topic", because it's a very subjective topic. I'll try to answer (here) the question myself if no-one answers the whole, and I'll ask very closed questions :</p>
  
  <ul>
  <li>How the three of them can "compile to" (external css, <code>&lt;style&gt;</code> tag, <code>style=</code> attributes) ?</li>
  <li>How the three of them can integrate smoothly with CRA (without too much tweaks and without ejecting) ?</li>
  <li>What about the OpenSource POV (age, community, plugins, backing) ?</li>
  <li>What about the performance ?</li>
  </ul>
  
  <p>Please I don't want this question closed, so I don't want some code-style opinions, and I want to avoid subjectives POVs.</p>
