You've mentioned the Dell Inspiron 14 Plus is often more expensive than the Dell Inspiron 15 3511, so here's what you should consider: If you need higher performance for tasks like video editing or gaming, the Inspiron 14 Plus usually offers better speed and graphics capabilities, making the extra cost worthwhile. However, if you prioritize a larger screen and are mainly using your laptop for regular activities such as browsing the internet, working with documents, or watching videos, the Inspiron 15 3511 might be a more cost-effective choice. Additionally, a larger screen size can typically result in less portability, so if you're frequently on the move, you may appreciate the smaller size of the Inspiron 14 Plus. Keep in mind, with a more powerful laptop, battery life can sometimes be shorter, so if long battery life is crucial, the Inspiron 15 3511 may be more suitable. Give Feedback

The Dell Inspiron 14 Plus and Dell Inspiron 15 3511 are both good for engineering and design, though the Dell Inspiron 14 Plus is somewhat better.
The Dell Inspiron 14 Plus is suitable for engineering and design due to its high-performance CPU, sufficient RAM, and integrated graphics that can support basic 3D tasks, along with a more color-accurate, high-resolution screen. In comparison, the Dell Inspiron 15 3511 also has a capable CPU and double the RAM for more intensive multitasking, but the screen quality is not as high, which may affect design work that relies on color precision.

The Dell Inspiron 14 Plus has a better screen than the Dell Inspiron 15 3511 for general use, gaming and AI, engineering and design, software development, and content creation.
If you primarily use your laptop for everyday tasks like browsing and office apps, the Dell Inspiron 14 Plus with its superior resolution and brightness will offer a clearer and more vibrant display. However, if your work involves precision in colors for tasks like photo editing, engineering, and design, the Inspiron 14 Plus would be advantageous again due to its better coverage of professional color gamuts ensuring greater color accuracy. But for those who are into 3D gaming where fast-paced visuals are crucial, neither laptop would be ideal as both have poor refresh rates, although the Inspiron 14 Plus might still provide a slightly better experience due to its higher resolution and panel quality.

"The Dell Inspiron 14 Plus is for power users on a budget. If you're looking to maximize CPU and GPU performance on your next 14-inch laptop, then consider the pricier Razer Blade 14 or Asus Zephyrus G14. If you're looking for a thin-and-light 14-inch Ultrabook, then the Asus Zenbook 14 or LG Gram 14 may be better options. For the best of both worlds, however, the Dell Inspiron 14 Plus 7420 rides a fine line between extreme performance and portability while keeping prices at reasonable levels. Frequent travelers who rely on performance beyond what the Core U-series and integrated graphics series can offer will find the Dell to be a solid solution."

"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."
