The <b>HTML srcset method</b> is the best. The HTML will be rewritten with <a href="http://www.w3.org/html/wg/drafts/srcset/w3c-srcset/">the srcset attribute</a> added to the img tags. Works with caching. Unfortunately, not all the browsers support it yet.<br /><br />
The <b>HTML Rewrite method</b> is one of the best methods. It replaces the images by the retina images - if available - in the HTML directly. It\'s tricky to use HTML caching with it however.<br /><br />
The <b>Retina.js method</b> is fail-safe and only uses one <a href="https://github.com/imulus/retinajs/">JavaScript file</a>. When a Retina Display is detected, requests for every images on the page will be sent to the server and the retina images will be retrieved if available. Requires a lot of bandwidth.<br /><br />
The <b>Retina-Images method</b> is efficient. The images will go through the <a href="https://github.com/Retina-Images/Retina-Images/">Retina-Images</a> handler. Caching systems might be an issue.
