Our Verdict
TCL 6 Series/R625 2019
TCL 8 Series 2019/Q825 QLED
The TCL 8 Series 2019/Q825 QLED is a bit better than the TCL 6 Series/R625 2019. The Q825 has better reflection handling and is more suitable for a room with a few extra lights, and thanks to its faster response time, fast-moving content has less blur. The R625, on the other hand, has a much lower input lag, so gaming feels very responsive, but its response time is slower than the Q825, which means there's more motion blur.
