Direct answer
There is no universal winner. The best platform supports the home's required devices, interfaces, programming complexity, service model, and future expansion while remaining comfortable for the household to use. Control4 emphasizes broad device integration and a consistent whole-home interface. Crestron Home supports deeply integrated residential control and extensive professional configuration. Savant emphasizes personalized scenes and polished control of entertainment, lighting, climate, and security.
Those are manufacturer positions, not proof that one platform is best for every project. Compare proposed interfaces, exact supported drivers, local versus cloud dependencies, upgrade policy, subscriptions, documentation, and available local support. Ask each integrator to demonstrate the household's five most important routines. Design, programming, and long-term service can be as consequential as the platform brand.
