Should I use React.createClass, ES6 Classes or stateless functional components?

React.createClass if you want mixins, automatic binding of "this.handleWhatever" methods, and Hot Module Replacement.

ES6 Classes if neither of these are a big deal to you, but you prefer classes and still want HMR.

Functional components of you want terse, testable, potentially vdom-agnostic UI components despite losing HMR capabilities (as of yet).

Is the issue with functional components that they blow away the state of any stateful components they contain with HMR?

If you install and run this Gist mini-project, you still get the HMR experience with the functional component:
