Real-world verdict

Different panel philosophies. The LG is a 27-inch 1440p 240 Hz OLED: unbeatable contrast and motion, gorgeous for games and consoles, but W-RGB subpixel fringing makes fine text slightly soft. The ASUS is a 27-inch 1440p 270 Hz fast IPS: razor-sharp text, no fringing, and excellent for competitive play where pixel clarity matters. Gaming immersion and HDR → LG OLED; productivity text and competitive clarity → ASUS fast IPS.
