The Acer Aspire 3 14 and the Dell Inspiron 15 3511 have differences that may affect your decision. The Acer, while generally less expensive, is smaller and more portable due to its 14-inch screen size but may have less powerful hardware or a smaller battery compared to the Dell. The Dell Inspiron 15 3511, with a 15.6-inch screen, likely offers a larger display for multitasking and possibly better performance, which can be advantageous for more demanding tasks. However, it may be heavier and less portable. If budget is a primary concern and you value portability for basic tasks, the Acer might suit you better. If you prefer a larger display and increased performance potential for complex applications, and don't mind spending a bit more, the Dell could be a better fit despite potentially shorter battery life or added weight. Consider your needs for performance, screen size, portability, and budget when making your choice. Give Feedback

For general use, the Acer Aspire 3 and Dell Inspiron 15 provide adequate visuals with their resolutions and brightness levels being suitable for everyday tasks like browsing and streaming, although their panel types may not offer the wide viewing angles and color reproduction of higher-end laptops. For engineering and design, both laptops have limitations in their color gamuts, meaning professionals may find colors are not as accurate or vibrant for precise work such as photo editing or CAD. With gaming and 3D applications, their lower refresh rates can result in less fluid motion and responsiveness, making them less ideal for fast-paced gaming or complex 3D rendering.

PCMag
Zachary Cuevas | November 2021
"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."
