Automatically controlling TOADS is a built-in feature of all Harmony remotes (that's the Smart State feature). The harmony dynamically figures out how to get from the current state to the desired state. To do this with another remote requires state memory (unless the device can be forced into a known state - but not all devices can do this) and a lot of custom code to compare the current state to the desired state and figure out how to get there.

With a harmony you say here is the list of inputs and here is the button(s) to cycle through them and this is the way the device behaves regarding the inputs.

Then you create an activity and tell it this activity needs input A for this device. The remote does everything else.

This is not an argument you can possibly win.
