Samsung CU8500 55" (Crystal UHD) vs TCL 6-Series R655 55" (Mini-LED QLED)
The Verdict
Samsung's CU8500 offers solid entry-level 4K performance at an attractive $479 price point, featuring HDR10+ support, 350-nit brightness, and ALLM gaming mode with 11ms input lag. However, TCL's 6-Series R655 ($749) substantially outperforms it across nearly every dimension: its mini-LED QLED panel delivers exceptional contrast with 1500-nit peak brightness, supports Dolby Vision HDR, includes 120Hz refresh rate with VRR for smooth gaming (7ms input lag), and provides superior audio with 30W Dolby Atmos sound. Connectivity advantages favor TCL with Wi-Fi 6, four HDMI ports, and Google TV's superior app ecosystem compared to Samsung's Tizen. While the Samsung excels as a budget-conscious choice with respectable specs, the TCL 6-Series represents significantly better overall value for those willing to invest $270 more, delivering flagship-level picture quality, gaming features, and smart platform capabilities that justify the premium.
