If you prioritize a dual-screen setup and higher refresh rates for smoother visuals in fast-paced applications, consider the ASUS Zenbook Duo. It offers a unique second display for multitasking and creative work, but has a shorter battery life and is slightly heavier, which may affect portability. Alternatively, if you're looking for more storage space, a larger primary screen, and a quieter, cooler system, the Dell Inspiron might be more suitable. It also tends to be more cost-effective and has a longer battery life, making it a good fit for general use and multimedia. Both models provide similar performance capabilities, with ample RAM and capable processors, but the ASUS could be more appealing for those wanting extra screen real estate for productivity.

Allen Ngo | May 2020
"The Asus ZenBook Duo's second screen is like the Apple Touch Bar, but better. Most would agree that having two screens instead of one can really boost productivity and the ZenBook Duo is no different in this regard. It's tough going back to just one screen after becoming accustomed to spacious dual-screen setups. For a laptop form factor, however, users will have to accept some compromises. Firstly, weight is the most obvious drawback as the system is several hundred grams heavier than a regular ZenBook 14. Additionally, colors on the second screen will not be as vivid as the main display."

Derek Sullivan | January 2023
"Compared to the previous year’s Inspiron, Dell upgraded the screen aspect ratio on this generation, but also transitioned to a more minimalistic centered keyboard flanked by up-firing speakers. The 16-inch screen is huge plus and I really appreciate the extra real estate without sacrificing the footprint much. This year’s model is a little larger than last, though, as the former model was already very small for a 15 incher."
