When choosing between the ASUS Vivobook 15X and the Lenovo IdeaPad Slim 5i, consider the following: the ASUS is slightly more expensive, but slightly lighter and has a longer battery life, making it more portable. On the other hand, the IdeaPad Slim 5i offers more RAM, which is crucial for smoother multitasking and better performance in intensive tasks. Both have similar screen sizes and quality, but the IdeaPad's screen is brighter and has a slightly higher resolution with a taller aspect ratio. Neither is designed for intensive gaming, but both can manage general use and less demanding engineering applications. If you require stronger performance for engineering tasks and can handle a bit more weight, the IdeaPad may suit you better, while the Vivobook is a solid choice for general use with easier portability.

The Lenovo IdeaPad Slim 5i has a better screen than the ASUS Vivobook 15X for general use, engineering and design, content creation, and software development.
For general use, both the ASUS Vivobook 15X and the Lenovo IdeaPad Slim 5i provide adequate clarity and visibility, but may lack in resolution or have lower brightness that could affect the viewing experience in well-lit environments. In engineering and design tasks, their displays may not cover a wide color gamut, resulting in less accurate color representation which is vital for precise visual work. Lastly, when it comes to 3D and gaming, their screens do not offer high refresh rates, leading to less fluid motion and a potential disadvantage for fast-paced visuals that benefit from smoother transitions.

How the ASUS Vivobook 15X and the Lenovo IdeaPad Slim 5i 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."
"The device is made for average work loads and if your work has a lot to do with online browsing, using apps that are not power-hungry and streaming videos. The looks are really good and the device in itself is not a heavy one. And with Intel 11th-gen Core processor, you might sail through most of your work without complaints."
