Our Verdict

Samsung Q70/Q70A QLED

Samsung Q80B [Q80, Q80BD] QLED

The Samsung Q70/Q70A QLED and the Samsung Q80B QLED are both good TVs with different strengths and weaknesses. Although the Q70A doesn't have a local dimming feature like the Q80B, it's still better for dark rooms because it displays deep blacks and has less blooming around bright objects. However, the Q80B gets brighter, especially in HDR, and it's a better choice for wide seating arrangements because it has a wider viewing angle. They each have HDMI 2.1 bandwidth, but the Q80B has it on all four inputs, while it's just limited to one input on the Q70A.
