Roku Ultra or Apple TV 4K: which should you buy? Apple's is faster, with no ads. Roku's is simpler. Here's where each wins, and the limit both share.
Short answer, from our guide's research, since we haven't tested them: Apple TV 4K for the most polished one, Roku Ultra for simple and less. But why buy either? Smart TV software slows down within a year or two, and TV makers stop updates after two or three years. Dedicated streamers like the Apple TV run on faster processors, and keep getting updates for five years or more.
They share a lot. Both support Dolby Vision, which tunes the picture scene by scene. Both do Dolby Atmos from streaming apps. Roku Ultra has an Ethernet port, and so does the 128 gigabyte Apple TV 4K, for a wired connection that beats Wi-Fi. And every big streaming service is on both.
The Apple TV 4K is the faster one, and its interface has no ads. It also matches your TV's frame rate automatically, which avoids judder, that stutter in slow camera pans. And AirPlay sends video from your Apple devices to the big screen.
Roku's strength is its interface. Our guide calls it the simplest and most neutral, with no lean toward one company's ecosystem. It also costs less. The catch? Roku has the most limited support for third party apps.
One limit for both. Roku has no lossless audio passthrough, and Apple doesn't support DTS. If you play ripped Blu-rays, the guide says get the NVIDIA Shield instead. Otherwise? Apple TV 4K for the most polished one. Roku Ultra for simple, and less.
