The Verdict

Gaming favors Hisense significantly,7ms input lag, VRR support, and 144Hz make it substantially better for console/PC gaming. Audio output is stronger on Hisense (30W vs 20W). Roku Plus compensates with lower price ($399 vs $649), lighter weight, more versatile voice assistant support, and Roku's intuitive interface. Both feature Wi-Fi 6, Dolby Vision/HDR10+, and 4K resolution. For gaming enthusiasts and picture quality seekers, Hisense U7K justifies its $250 premium with superior specs.
