If you prioritize performance and multitasking for tasks like 3D rendering, machine learning, or gaming, the ASUS Zenbook Duo 14 with its dual-screen setup and generally higher specs is a strong option, but with a higher cost. For everyday use like browsing, office work, and media consumption, the Dell Inspiron 15 3511 offers good value, includes a larger screen, and is more budget-friendly but may not handle intensive tasks as well. The Zenbook Duo is less portable due to its unique design, while the Inspiron is more traditional and easier to carry. Balancing budget against requirements is key; if high-end tasks aren't a necessity, the Dell Inspiron may suffice and save money. Give Feedback

The ASUS Zenbook Duo 14 has a better screen than the Dell Inspiron 15 3511 for general use, gaming and AI, and engineering and design, while the Dell Inspiron 15 3511 has a better screen for content creation, and software development.
The ASUS Zenbook Duo 14's higher resolution and panel type provide sharp and vibrant visuals for everyday tasks and detail-oriented work such as engineering and design, where its wider color gamuts help ensure accurate color representation. However, its refresh rate isn't high enough for the smooth visuals demanded by gaming and 3D applications. In contrast, the Dell Inspiron 15 3511, with decent resolution and panel quality, offers adequate display performance for general tasks and less color-sensitive engineering work, but like the ASUS, falls short for gaming and 3D due to a lower refresh rate.

How the ASUS Zenbook Duo 14 and the Dell Inspiron 15 3511 compare to other laptops
"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."
"The Dell Inspiron 15 3000 (3511) is a solid, if unremarkable, 15-inch budget laptop. It improves on many of the issues we had with the previous 3505 model, and with the inclusion of Windows 11, the 3511 is already a step above its competition. The lack of a USB-C port, the subpar speakers, and the dim display are drawbacks to factor in, but it's still one of the better 15-inch budget laptops on the market, especially when you consider it's under $400."
