Sony X90L 65" vs TCL 6-Series R655 55" (Mini-LED QLED)
The Verdict
Sony's X90L 65" commands premium pricing with its larger screen size, superior Cognitive Processor XR upscaling, and refined Full Array LED implementation delivering exceptional contrast. Meanwhile, TCL's 6-Series R655 55" punches above its weight class with Mini-LED QLED technology, actually achieving brighter peak nits (1500 vs 1300), faster Wi-Fi 6 connectivity, and more powerful 30W speakers,all at $350 less. Gaming performance favors TCL slightly with 7ms input lag versus Sony's 8ms. However, Sony's 65-inch screen provides dramatically more immersive viewing real estate for most living rooms, and its advanced processor handles upscaling for non-native content more intelligently. For those prioritizing screen size and processing sophistication, Sony wins. Budget-conscious buyers wanting exceptional brightness and gaming specs in a compact form should choose TCL.
