Our Verdict
Samsung QN85A
TCL 6 Series/R646 2021 QLED
The Samsung QN85A and the TCL 6 Series/R646 2021 QLED are both great TVs, and the best one for you depends on your specific viewing conditions. The TCL has much deeper blacks, resulting in significantly better picture quality in a dark room, with less blooming around bright objects and very little clouding in dark scenes. The Samsung gets brighter and has improved reflection handling, so it's a better choice for well-lit rooms.
