Our Verdict
ASUS Zenbook S 16 UM5606 (2024)
Dell 16 Plus (2025)
The ASUS Zenbook S 16 UM5606 (2024) is better than the Dell 16 Plus (2025) overall. The ASUS has a more premium build, a more tactile keyboard, a more responsive touchpad, and a higher quality webcam. You can achieve better performance with the ASUS if you opt for the top-end AMD Ryzen AI 9 CPU, but the battery life may not be as good as Dell's. Also, keep in mind that the ASUS' OLED display flickers at 480Hz, which might bother some people.
