Our Verdict
Samsung Q800T 8k QLED
Samsung Q90/Q90T QLED
The Samsung Q90T QLED is better than the Samsung Q800T 8k QLED. The Q90T is a 4k TV that has a better contrast ratio, slightly better uniformity, much better reflection handling, better out-of-the-box color accuracy, and a quicker response time. Both TVs have one HDMI 2.1 input, so they're both future-proof, but the Q800T can display 8k content.
