html - Self-closing tags (void elements) in HTML5

Step 6 of 8.1.2.1 Start tags of the HTML5 spec says that void elements may have a single / character. I think this is so it's easier to migrate sites that are XHTML over to HTML5.

What's the best practice?

E.g., if I'm making a website with HTML5 (<!DOCTYPE html>), which should I do?

  1. without the slash

    <meta http-equiv="content-type" content="text/html; charset=utf-8">
    
  2. with the slash

    <meta http-equiv="content-type" content="text/html; charset=utf-8" />
    

If both render correctly on all browsers, then I'm assuming (1) without the slash is the way to go since it's more HTML5.

There is no consensus on best practice, and according to the author of the spec, Ian Hickson, it does not matter.
