What's New section
You'll see that they are literally identical and talks about the other i.e in Microsoft Word page they have mentioned about Excel's new features and in Microsoft Excel page they have mentioned about Word's new features too.

Premium feature related to Charts  


  Advanced editing of charts: precise control over chart display options that allow you to change elements of the chart such as data labels and the legend are paid features.
