Apple today provided developers with the second beta of an upcoming 9.2.1 update to tvOS, the operating system designed to run on the fourth-generation Apple TV. tvOS 9.2.1 is a minor update that comes one month after the launch of tvOS 9.2, a major update that introduced a range of features from Bluetooth keyboard support and dictation to Siri search for the App Store and app folders.

tvOS betas are more difficult to install than beta updates for iOS and OS X. Installing the tvOS beta requires the Apple TV to be connected to a computer with a USB-C to USB-A cable, with the software downloaded and installed via iTunes or Apple Configurator. Those who have already installed the first tvOS 9.2.1 beta will be able to update to the second beta over the air.
As a minor 9.x.x update, tvOS 9.2.1 likely focuses on bug fixes and performance updates to address issues discovered since the release of tvOS 9.2. No new outward-facing changes were found in the first tvOS 9.2.1 beta, but should any new features pop up in beta 2, we will list them below.

Latency will be lower on copper.
I seriously doubt the need for low latency for movies and casual games though, so go for WiFi, just make sure your router and setup are decent
But practically speaking the wired is going to be much more consistent and not subject to significant interference.
