The Verdict
Sony's X80K delivers superior smart TV integration with Google TV's polish and Dolby Atmos audio, making it the more refined entertainment hub at $699. Vizio's M7 Q-Series counters with better raw display performance,600 nits brightness versus Sony's 500, faster gaming response (12ms vs 16ms input lag), and Wi-Fi 6 connectivity, all at a compelling $200 discount. Picture quality favors Vizio's Quantum Color technology and HDR10+ support, while Sony excels in software fluidity and audio immersion.
