The TCL QM8 65 Inch wins for most buyers due to its 2025 Mini-LED upgrades delivering higher brightness (around 2000 nits peak per RTINGS) and better motion clarity than the 2023 Hisense U8N. The U8N remains capable for dark-room use but trails in longevity and app optimization. Choose the TCL if you want current-generation performance; the Hisense only if found at a steep discount.
