The example on the right adds more value over the one on the left. The example on the right uses a column chart instead of a slicer. The benefit of this is you can communicate more information to the user than you can with the static slicer. In this case I am displaying the total value of each of the scenarios which means it is easy to see the relative difference between them. And this all happens while still providing slicer capabilities thanks to the powerful cross filter feature in Power BI. This is what I mean by adding value by thinking outside your old paradigms.
Definitely read the comments on this one; they are full of great questions and suggestions.
