If your only metric is infinite contrast for watching movies in a dark room, OLED wins. But claiming any Asus or Lenovo OLED is universally "better" ignores the realities of using a laptop for daily productivity.
Many of the OLED panels in laptops use non-standard subpixel layouts that cause noticeable text fringing, which can be distracting when you're staring at documents, data, or code all day. The OLED panels also often rely on low-frequency PWM dimming that causes eye strain over long sessions in some people. Combine that with the battery hit you take anytime you display a white background, and Apple’s highly efficient, factory-calibrated LCDs remain more consistent, color-accurate, and comfortable for getting work done.
Apple would have already switched to OLED screens in its laptops if they were clearly better than the LCDs Apple uses. OLED is better in some ways, but not inherently better just because it's OLED.
