Gaming performance is virtually identical with 7ms input lag, VRR, and ALLM enabled on both models. Key differences emerge in refresh rate capability,the Hisense reaches 144Hz versus TCL's 120Hz,and connectivity features. Hisense includes dual USB ports and Bluetooth 5.1, while TCL offers a more robust VESA mount pattern (300x300mm vs 200x200mm). Audio specifications match at 30W with Dolby Atmos on both. The $100 price advantage favors Hisense, which also provides slightly better gaming flexibility. TCL's sturdier mounting options appeal to wall-mount prioritization.
