Our Verdict

LG C4 OLED

Sony X90L/X90CL

The LG C4 OLED is much better than the Sony X90L/X90CL, making the LG the better choice for almost anyone. The Sony does have the edge in a few ways; it's brighter than the LG in SDR, and while both TVs perform similarly in HDR when watching actual content, the Sony maintains its HDR brightness in Game Mode, while the LG is noticeably dimmer. Still, the LG has vastly better contrast, leading to a much more impact viewing experience in dark rooms. Plus, its far superior reflection handling means it compensates for its lower brightness numbers in Game Mode and SDR content by handling reflections better than Sony. Finally, the LG has a better viewing angle, making it better for hosting large viewing parties.
