Our Verdict
LG B3 OLED
Samsung S90C OLED
The Samsung S90C OLED and LG B3 OLED are both amazing TVs, and while the LG has a few features that the Samsung doesn't have, the S90C is the better TV overall. The Samsung gets much brighter in HDR and SDR, with a wider color gamut and better color volume, so all content looks significantly more vibrant on the Samsung. It also has four full HDMI 2.1 bandwidth ports, all capable of up to 4k @ 144Hz (120Hz on the 83-inch model), making it the better TV for gamers. The B3 does have better image processing, supports Dolby Vision HDR, and passes through DTS audio formats, making it enticing for home entertainment fans.
