From time to time the Logitech Harmony Smart Control package goes on sale from various vendors and people typically jump all over it mostly for the Harmony Hub. I myself have a stack of the included remotes that have never even been used. If you are looking to add voice and app control to your AV Gear then the Harmony Smart Control package is the way to go because it gets you the Hub for less than you can typically purchase the standalone hub for.
