Our Verdict
Lenovo Yoga 9i 2-in-1 Aura Edition 14 (2025)
ASUS Zenbook DUO UX8406 14 (2025)
The Lenovo Yoga 9i 2-in-1 Aura Edition 14 (2025) and the ASUS Zenbook DUO UX8406 14 (2025) are both premium convertible laptops; however, the Yoga only has one screen, while the Zenbook has two. The Zenbook DUO is obviously the better choice if you need the second screen, but remember that running both displays will significantly impact battery life. You get better CPU performance on the Zenbook DUO; however, the Yoga delivers a better overall user experience, as it has a higher quality webcam, better-sounding speakers, and lower fan noise.
