Our Verdict

LG GX OLED

Sony A9S OLED

The Sony A9S OLED and the LG GX OLED are very similar overall as they're both 4k OLED TVs. However, the LG is a bit better because it can display a 4k @ 120Hz signal and has HDMI 2.1 ports. It's also a better choice for gaming due to its lower input lag and VRR support. The Sony has better accuracy out of the box, so you may not need to calibrate it for accurate color reproduction. It gets brighter in SDR to combat glare, but the Automatic Brightness Limiter is a bit more aggressive, causing more brightness variability.
