What’s the use of Jade or Handlebars when writing AngularJs apps

I use Jade to generate templates consumed by AngularJS because I hate writing plain HTML. It looks something like:

.control-group(
  ng-form
  name="emailGroup"
  ng-class="{"ng-error": emailGroup.$invalid}"
)
  label.control-label Email
  .controls
    input(
      type="email"
      ng-model="user.email"
      required
      placeholder="you@example.com"
      focus-on='focusEmail'
    )

… which I think is a lot cleaner than plain HTML.
