Our Verdict
LG B3 OLED
LG C3 OLED
The LG C3 OLED and the LG B3 OLED are similar TVs with nearly identical feature sets, but the C3 is better overall. The C3 gets much brighter in HDR and SDR, has better image processing due to its better 4k processor, and has four full HDMI 2.1 bandwidth ports. Inversely, the B3 has two HDMI 2.1 bandwidth ports, one of which also doubles as the eARC port, so you'll need to buy an HDMI 2.1 switch if you have multiple HDMI 2.1 devices.
