A:Answer From my experience, it gives you access to Apple's gaming and fitness services (Apple Arcade and Fitness+). It allows you to use your HomePod(s) or HomePod mini(s) as TV speakers for a good surround sound system. Apple TV 4K (2021) comes with redesigned 'Siri Command Remote' also. But most importantly, 'Privacy'. Apple takes the protection of your person information very sincerely, which is a big reason to use Apple's streaming hardware over just using its services on a third-party TV,Smart TV or dongle. If you don't have an Apple TV streaming box, then your streaming activity and account information isn't monitored by Apple, but by the hardware companies that are running its software — and they likely don't have the same rigorous standards of protecting your information as Apple. You can also connect your 'AirPods, AirPods Pro or AirPods Max' for private listening on your TV. Apple TV HD runs more smoothly which a Stronger Processor than a Smart TV which lags for better streaming. It also connects to your 'Smart Home Hub'. Last, you can put your own 'Personal Screensavers' on your TV when you're away. It was a great choice for me to purchase.
