The best option is the third-generation 128 GB Apple TV 4K. For only a little more than the 64 GB model, it offers double the storage, an Ethernet port, and support for the Thread home automation protocol. It’s well worth the slight extra cost.

Make sure you pair it with a high-speed HDMI cable to take full advantage of HDR and other high-end visual features. Yes, the cable matters!

Do you need an Apple TV 4K?
Once upon a time, you needed an Apple TV if you wanted to watch iTunes content on the big screen. That’s no longer the case. The Apple TV app is available for every major smart TV platform, and most TVs are “smart” these days. So you may not need one at all.
Some reasons to consider a standalone Apple TV:
- Smart TV platforms are notorious for spying on you. Apple offers better privacy.
- An Apple TV can act as a HomeKit hub, letting you use home automation while away from home.
- Built-in Siri.
- Better performance.
- Native support for HomePods and AirPods.
Do you need to upgrade?
If you have an older Apple TV, should you upgrade?
- Second- or Third-Generation: Yes, upgrade.
- Apple TV HD (any generation): Yes, an upgrade could be worthwhile. But if you don’t have a 4K TV and are happy with your picture quality and performance, you can hold off.
- First-Generation 4K: An upgrade could be worthwhile for more storage space, better performance, and the improved Siri Remote, but there’s no rush.
- Second-Generation 4K: No need to upgrade unless you need more storage space.
A budget alternative to the Apple TV
We like Roku’s software for its ease of use and wide app support. The Roku Express 4K delivers excellent picture quality (and an HDMI cable) for a fraction of the cost of the Apple TV. Plus, Roku features the Apple TV app. However, be aware that Roku’s software constantly sends your activity back to Roku’s servers.
