Our Verdict

ASUS Zenbook A14 UX3407 (2025)

Dell 14 Plus 2-in-1 (2025)

Although the Dell 14 Plus 2-in-1 (2025) and the ASUS Zenbook A14 UX3407 (2025) are both 14-inch Windows laptops, they're quite different. The Dell is a convertible with stylus support, while the ASUS is a more traditional clamshell model. In terms of the overall user experience, the ASUS is better, as it has a nicer OLED display, a more comfortable keyboard, and a more responsive touchpad. The most important thing to know about these two laptops is that the Dell runs on an Intel x86 chip, while the ASUS runs on Qualcomm's ARM-based SoC. For most people, the difference in performance won't matter much, as these chips can easily handle general productivity tasks; however, keep in mind that many programs don't run natively on ARM-based SoCs, so you'll want to check that the apps you use are compatible if you're considering the ASUS. The upside is that the Qualcomm chips are very power efficient, giving you much longer battery life on the ASUS.
