The ASUS Zenbook 14X is less expensive with a vivid OLED screen, lighter weight and higher portability, making it suitable for on-the-go use and general tasks. However, the Lenovo Legion Slim 5i, while heavier and not as portable, has a more powerful GPU and higher storage capacity, which is essential for gaming, 3D rendering, and engineering software. The Legion also has longer battery life and is better equipped for intensive tasks. Consider the Zenbook if you prioritize mobility and cost-effectiveness and the Legion if performance in demanding applications and gaming is your priority. Give Feedback

The Lenovo Legion Slim 5i is very good for gaming and AI, while the ASUS Zenbook 14X is only fair.
The Lenovo Legion Slim 5i excels in gaming and 3D applications because it is equipped with a more powerful Nvidia RTX 4060 graphics card and a higher screen refresh rate of 165, compared to the Asus Zenbook 14X which has a less capable Nvidia MX550 graphics card and a lower refresh rate of 90. While both laptops have quality displays and capable processors, the GPU and refresh rate are the more critical factors for gaming and 3D performance, making the Legion Slim 5i the better choice for those specific tasks.

The Lenovo Legion Slim 5i is very good for engineering and design, while the ASUS Zenbook 14X is good.
The Lenovo Legion Slim 5i excels for engineering and design owing to its more powerful Intel i7 processor, a superior Nvidia RTX GPU, and a larger, faster-refreshing IPS screen, which are crucial for such tasks, while the ASUS Zenbook 14X, with a less capable Nvidia MX GPU and a smaller OLED screen, might offer less raw power but better screen color accuracy which can be important for design work. However, the Zenbook is lighter and thus more portable, has a higher pixel density for sharper images, and boasts an OLED screen which generally presents more vibrant colors and deeper blacks.

The ASUS Zenbook 14X has a better screen than the Lenovo Legion Slim 5i for general use, and engineering and design, while the Lenovo Legion Slim 5i has a better screen for gaming and AI, content creation, and software development.
The ASUS Zenbook 14X boasts a vivid display with high resolution, making it ideal for day-to-day tasks and professionals who work with color-sensitive applications like photo editing or CAD software. However, its lower refresh rate holds it back for gaming or 3D work, where fluid motion is key. The Lenovo Legion Slim 5i offers a sound balance, providing quality visuals for both everyday users and those in creative fields, yet it might fall short for gamers or 3D designers seeking the smoothest visual experience.

The Lenovo Legion Slim 5i and ASUS Zenbook 14X are both good for general use.
The ASUS Zenbook 14X is well-suited for general use due to its combination of a strong CPU, sufficient RAM, and a high-quality OLED screen, all packaged in a lightweight, highly portable design with decent battery life. On the other hand, the Lenovo Legion Slim 5i, while also having a strong CPU and adequate RAM, features a larger, high-refresh rate screen and superior heat management, making it heavier but more versatile for diverse tasks, albeit with better battery life. Both have ample storage and good keyboard and speaker quality, but the Legion's gaming-oriented design may affect its appeal for non-gaming general use.

How the ASUS Zenbook 14X and the Lenovo Legion Slim 5i compare to other laptops
"With the Zenbook 14X, Asus has a 14-incher in its range that is - mostly - a joy to use. First, there is the colorful OLED panel with 3K resolution that displays the sRGB and DCI-P3 color spaces. The Zenbook is also at the forefront in terms of workmanship, input devices and connections with 2x Thunderbolt 4 ports and a generous keyboard layout. A pleasure to use, the Zenbook 14X is a solid, very well-built subnotebook that sits well on the table. A runtime of five hours, however, is below average for a high-end subnotebook nowadays. The OLED screensaver causes increased power consumption when in idle mode."
"The Lenovo Legion Slim 5 Gen 8 acknowledges that a gaming laptop doesn’t have to be as thick as possible and can still ensure adequate cooling when the muscles need flexing. To this end, in the Slim 5 Gen 8, it finds a neat balance of refined, trimmed-down design that still lets its internals cruise (even above their max power ratings). Lenovo then added in some high-end build quality with an altogether excellent keyboard that’s useful for both work and play."
