The ASUS ZenBook Pro 14 Duo is a midrange laptop which is much more expensive than the budget-friendly Dell Inspiron 15 3525. If you need high performance for 3D work, machine learning, and engineering, and value a premium display with high resolution, touch capability, and excellent color coverage, the ASUS would be an excellent choice, though it's heavier and with a slightly shorter battery life. On the other hand, the Dell Inspiron offers decent performance for general use and is lighter, which may make it preferable if you prioritize portability and value. Both seem comparable in terms of battery life for typical usage. Give Feedback

"The Zenbook Pro 14 Duo OLED is a well-tuned instrument for content creators, excelling at a range of general office tasks as well as tasks that require a little more grunt like encoding and 3D rendering. The big attraction is the laptop’s dual displays. They’re the best ones we’ve used in an Asus Zenbook Duo laptop to date with a spate of year-on-year improvements that make the visuals more striking and the cross-screen integration easier than ever before."

"Dell's Inspiron 15 (3525) is a peppy-enough and affordable-enough home or remote work machine, but it's not very ambitious; it does little to go beyond the basics. More the concern: It’s readily overshadowed by a number of machines that outperform and outclass it. Even if the Inspiron can get the job done today, its competition has the mettle to keep doing the job tomorrow in a way the Inspiron simply can’t promise. Many of its slightly higher-end rivals have to be on sale (and frequently are) to match it on price, but the Inspiron 15 (3525) is outclassed even by some similarly priced options, making it a difficult recommendation."
