Yes, it is true that a rigid brace would reduce the deflection more than dampers but you would not see the huge increase in the stresses in the model that would also be generated by adding rigid braces. The biggest benefit of adding dampers to a building is to reduce deflection and stress simultaneously. Rigid braces reduce deflection while making the building stiffer and attracting more earthquake load.

I'm a believer in the usefulness of dampers, but if you're trying to demonstrate that with this setup you'll leave many people thinking, "Are they helping because they are 'shock absorbers' or would a rigid support just do the same thing?" Anything is going to be more structurally sound with proper supports. This demo fails to properly show the difference.
