LG QNED80 55" vs TCL 5-Series S555 65" (QLED)
The Verdict
Both TVs deliver strong value for budget-conscious shoppers, but they cater to different priorities. LG's QNED80 excels with superior QNED technology and LG's polished webOS 24 interface with multi-assistant support (ThinQ AI, Alexa, Google), plus superior brightness at 700 nits and LG's acclaimed α8 processor. TCL's 5-Series S555 counters with a larger 65-inch screen versus LG's 55-inch, better gaming performance (8ms vs 10ms input lag), slightly higher peak brightness (800 nits), and Wi-Fi 6 connectivity. Audio is comparable (20W vs 24W), though neither excels here. Gaming features match across VRR and ALLM support. For picture quality enthusiasts prioritizing premium display technology and software refinement in a compact form factor, the LG edges ahead despite the premium. Value-focused buyers wanting maximum screen real estate and gaming responsiveness should choose the TCL.
