Samsung Q70C [Q70, Q70CD] QLED vs Samsung CU8000 Side-by-Side TV Comparison

The Samsung Q70C QLED is better than the Samsung CU8000. While the Q70C still lacks local dimming, it has a much deeper native contrast ratio than the CU8000, so watching content in a dark room is a better experience on the Q70C. It's also better for bright rooms due to its higher peak brightness in HDR and SDR. It's the better TV for gamers due to its faster response time alongside full 4k @ 120Hz support with VRR, while the CU8000 is limited to 4k @ 60Hz with no VRR. Surprisingly, the cheaper CU8000 has much better low-quality content smoothing, so content from streaming apps will look a bit better on it as it does a better job of clearing out compression artifacts.
