The LG M4 OLED Wireless 97 wins for users needing a massive screen and clean wireless setup, beating the C4 on screen size by 42 inches and adding wireless video per LG specs. The C4 OLED 55 remains the practical pick for most rooms due to lower cost and easier placement. C4 trails the M4 on design flexibility but matches it on core picture quality metrics from RTINGS and CNET reviews.
