Our Verdict
Samsung Q70T
Samsung Q90/Q90T QLED
The Samsung Q90/Q90T QLED is higher in the Samsung lineup than the Samsung Q70T, so it has much better performance. The Q90T has a local dimming feature, which the Q70T doesn't, allowing it to display deeper blacks. The Q90T gets brighter and has wider viewing angles thanks to Samsung's 'Ultra Viewing Angle' layer as well. In terms of gaming, they each have a 120Hz panel and VRR support, but the Q90T has a much quicker response time.
