The ASUS Vivobook 15X is notably less expensive, lighter, and has a white backlit keyboard. It has an AMD Ryzen 5 processor with integrated graphics, making it suitable for general use and lighter tasks. On the other hand, the Lenovo Legion Slim 7 is a midrange laptop with a higher price but comes with a more powerful AMD Ryzen 7 processor and Nvidia RTX 3060 graphics, fitting for intensive gaming, 3D rendering, and engineering software. It also has a higher refresh rate display and RGB backlit keyboard. If budget is a constraint and your tasks are more basic, the Vivobook is a solid choice; however, for more demanding tasks, the Legion Slim 7 with its enhanced performance and features may be worth the investment.

The Lenovo Legion Slim 7 15.6" and ASUS Vivobook 15X are both good for general use, though the Lenovo Legion Slim 7 15.6" is somewhat better.
The Lenovo Legion Slim 7 has higher RAM capacity, a more powerful processor, and better screen quality, which contributes to its suitability for general use, despite being less portable and slightly heavier compared to the ASUS Vivobook 15X. While the Vivobook is more portable and has a fair screen quality, its lower RAM, weaker CPU, and less impressive screen specifications place it in the fair category for general use.

The Lenovo Legion Slim 7 15.6" is good for engineering and design, while the ASUS Vivobook 15X is only fair.
The ASUS Vivobook 15X may be deemed fair for engineering and design because its processor, RAM, and integrated GPU are adequate for basic tasks, but may struggle with more demanding applications, and although it has a high-resolution screen, color accuracy is modest. In contrast, the Lenovo Legion Slim 7 has a more powerful CPU and GPU, double the RAM for multitasking, and a superior screen with higher color accuracy and brightness, making it good for complex engineering and design work; however, these gains come at the cost of slightly less portability and increased weight.

The Lenovo Legion Slim 7 has a better screen than the ASUS Vivobook 15X for general use, gaming and AI, engineering and design, content creation, and software development.
The ASUS Vivobook 15X has a display that provides adequate resolution and brightness suitable for everyday tasks and work in engineering, but its limited color gamut might not fully satisfy professionals who rely on precise color work. The Lenovo Legion Slim 7 has a display with higher resolution and better color accuracy, making it more suitable for detailed engineering and design work, but its lower refresh rate means it's not ideal for gaming or 3D work that benefits from smoother visuals. Since both laptops have less than optimal refresh rates for gaming and 3D tasks, enthusiasts in those areas may prefer other models specifically tailored for higher frame rates.

"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 Lenovo Legion Slim 7 is a slim Legion notebook that is just as excellent with Nvidia & Intel. However, the Legion Slim 7i slightly sullied by lacklustre battery life. You get a slim aluminium chassis, great input devices, decent port selection, fast high-quality WQXGA display and great performance. Supporting Thunderbolt 4 is one advantage of the Intel/Nvidia model tested in this review. Moreover, this variant has slightly higher CPU performance as well as better GPU performance in certain applications (e.g. CUDA-based apps). The Lenovo Legion S7i is thin, premium and performant – but less efficient than its AMD counterpart."
