If portability and battery life are key for you, consider the ASUS Zenbook 13 because it is lighter and offers longer battery life. However, if you need a laptop with higher performance for 3D rendering, machine learning, or gaming, the Lenovo Legion Slim 7 has a stronger processor and dedicated graphics card, but it's heavier and has shorter battery life. The Lenovo's larger screen and higher resolution are beneficial for engineering and creative work, albeit making it less portable than the ASUS. The Zenbook's OLED display excels in color accuracy for general use, but for high refresh rates needed in fast-motion scenarios like gaming, the Legion is superior. The increased storage and RAM in the Lenovo are also advantageous for intensive tasks, though this comes with a higher price. Give Feedback

The Lenovo Legion Slim 7 16" is very good for general use, while the ASUS Zenbook 13 is good.
The ASUS Zenbook 13 offers a balance of performance and portability with its light weight and OLED screen, but the Lenovo Legion Slim 7 16" excels with a more powerful CPU and RAM, larger and high refresh rate screen, all contributing to a smoother and richer general use experience, despite its heavier weight and slightly lower battery life. Both laptops have high-quality screens and good battery life, but the Legion's superior hardware makes it very good for general use, while the Zenbook's focus on portability and efficiency makes it simply good for the same tasks.

The Lenovo Legion Slim 7 has a better screen than the ASUS Zenbook 13 for general use, gaming and AI, content creation, and software development.
When selecting a laptop for general use, the ASUS Zenbook 13, with its sharp resolution and bright display, makes reading text and viewing media a pleasure. For engineering and design work, this laptop's color accuracy across different spectrums like DCI-P3 and Adobe RGB ensures that the colors you see are precise, which is critical for professionals in these fields. However, for gaming and 3D applications, the ASUS may not be ideal because its refresh rate isn't as high as what's typically desired for these activities, where smooth motion is key for an immersive experience.

"The Asus ZenBook 13 is a compact 13-inch laptop with a fast Ryzen 7 5800U and OLED display. The subnotebook is also light and the modern design is convincing. The selection of high-quality materials make the device not only light, but also very stable. In addition, the visuals and haptics of the device offers a high-quality impression. The AMD Ryzen 7 5800U is a very good fit for the ZenBook 13, ensuring a high performance in the test. However, in terms of the 3D performance, we also notice that the Vega architecture is beginning to hit its limits."
"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."
