The ASUS Vivobook 15X has a better screen than the Dell Inspiron 15 3520 for software development, while the Dell Inspiron 15 3520 has a better screen for general use, gaming and AI, and engineering and design.
Both the ASUS Vivobook 15X and Dell Inspiron 15 3520 have displays that are adequate for tasks like browsing the web and watching videos, which makes them suitable for general use despite their average brightness and resolution. However, for engineering and design where precise colors are critical, the lack of wider color gamuts in these laptops means they don't uphold the high standards needed for professional color work. Their screens fall short for gaming and 3D applications due to low refresh rates, with resolution and panel type being less of a concern, but still contributing to a less than optimal experience for fast-paced visual content.

The Dell Inspiron 15 3520 and ASUS Vivobook 15X are both only fair for gaming and AI.
The ASUS Vivobook 15X has a dedicated GPU and a high screen refresh rate, which are very important for gaming and 3D tasks, providing smooth visuals and better performance. Meanwhile, the Dell Inspiron 15 3520, while also having a dedicated GPU, may have a lower screen refresh rate, but it compensates with a decent CPU and good screen quality, making it a competent choice for less demanding gaming and 3D applications.

The Dell Inspiron 15 3520 and ASUS Vivobook 15X are both only fair for engineering and design.
The ASUS Vivobook 15X and the Dell Inspiron 15 3520 are considered fair for engineering and design due to their adequate CPU performance, sufficient RAM for basic tasks, and integrated graphics, which are not optimized for demanding graphics work but can handle moderate design tasks. However, the Vivobook 15X offers a marginally brighter screen and higher contrast, which can improve visibility in design applications, while the Inspiron 15 stands out with its higher refresh rate display, which could provide smoother visuals, assuming the integrated GPU can leverage it.

How the ASUS Vivobook 15X and the Dell Inspiron 15 3520 compare to other laptops
"All in all, my day on the Vivobook had its ups and downs. It is a really pretty and well-built device, and it had all of the functionality I needed to get me through my browser-based workload. But the speakers weren’t my favorite, and the battery life was just too short."
"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. Plus, those alternatives are much more enjoyable after work."
