The Verdict

LG's OLED C3 represents a premium tier of television technology, featuring an OLED Evo panel with exceptional 900-nit peak brightness, 120Hz refresh rate, and 6ms input lag,ideal for both cinematic content and competitive gaming. Roku Plus Series delivers solid value at its $399 price point with QLED technology, Dolby Vision support, and adequate 60Hz performance, though its 700-nit brightness and 13ms input lag reveal budget-tier limitations. Build quality heavily favors LG with thinner construction (1.8" vs 10.2"), superior 2.2ch audio (40W vs 20W), and full gaming features including VRR. Roku's key advantage lies in software simplicity and multi-assistant flexibility. For discerning viewers prioritizing picture quality, gaming, and longevity, the C3 justifies its premium cost with OLED's infinite contrast and superior motion handling. Budget-conscious buyers accepting compromises in brightness and refresh rates will find Roku acceptable, but LG delivers substantially better performance across nearly every technical metric.
