Final Thoughts: Which One Should You Buy?
If your home already runs on Apple devices like the iPhone, HomePod mini, and HomeKit lights or sensors, the Apple TV 4K is the most logical upgrade. It acts as the central hub for all your automations, supporting Thread networking, secure video streaming, and native Siri control — making it the best streamer for HomeKit in connected Apple households.
Meanwhile, the Roku Ultra still offers excellent value for users seeking fast, affordable streaming with access to a wide range of apps. However, its limited HomeKit compatibility makes it less suitable for automation-focused setups or homes that rely heavily on Apple’s ecosystem.
