Roku Plus Series 55" vs TCL S4 55"
The Verdict
Both 55-inch 4K TVs deliver solid value, but serve different priorities. Roku Plus Series excels with superior brightness (700 nits vs 400), QLED panel technology, Dolby Atmos audio, and faster gaming performance (13ms input lag vs 30ms). Wi-Fi 6 connectivity and four HDMI ports provide better future-proofing. TCL S4 undercuts by $120, using a standard LED panel with softer picture quality but includes Google TV's refined interface and broader app ecosystem. Audio output drops to 15 watts without Atmos support, while gaming responsiveness lags noticeably. For movie enthusiasts and console gamers, Roku's brighter, more vibrant display and superior motion handling justify the premium. Budget-conscious buyers prioritizing streaming and casual viewing will appreciate TCL's Google TV platform and lower entry price. Roku Plus Series earns the edge for overall feature density and performance.
