Our Verdict
Samsung Q70/Q70T QLED
LG NANO90 2020
The Samsung Q70/Q70T QLED and the LG NANO90 2020 are both good TVs with different panel types. The Samsung has a VA panel that allows it to display much deeper blacks than the LG, so it's better suited for watching movies in dark rooms. However, the LG's IPS panel has wider viewing angles, making it a better choice for wide seating areas.
