Let's optimize this:

```js
var len = a.length;
for ( var i = 0; i < len; i++) {
  if (!Utils.probablyMatches(a[i], b[i])) {
    return true;
  }
}
```

The problem is that `Utils.probablyMatches` is only for phone numbers, so you can't actually share this functionality with the content comparisons. 

We absolutely need to upgrade our draft mocks in the tests to reflect real world draft content.
