If you prioritize portability and better three-dimensional rendering or machine learning tasks, opt for the Lenovo Legion Slim 7, which also offers superior screen refresh rate for fast-paced gaming. However, the Asus Zenbook Pro 15 might be the better choice if you value longer battery life for general use, an OLED touchscreen for vivid colors, and a slightly better build quality for durability, while still providing good gaming performance. The Lenovo tends towards a gaming laptop look and has a higher quality keyboard, while the Asus doubles as a premium business laptop with a more professional appearance. Both have similar performance capabilities, but the Lenovo is slightly less expensive and the Asus is slightly more expensive, both offering midrange pricing. Give Feedback

The Lenovo Legion Slim 7 15.6" is good for gaming and AI, while the ASUS Zenbook Pro 15 is only fair.
The Lenovo Legion Slim 7 with its Nvidia RTX 3060 graphics card and a higher screen refresh rate of 165Hz is better suited for gaming and 3D applications than the ASUS Zenbook Pro 15, which has a lower-tier Nvidia RTX 3050 Ti and operates at a 60Hz refresh rate. Though both laptops have similar CPUs and screen qualities, the GPU and refresh rate are the definitive factors in gaming and 3D performance, giving the Lenovo an edge in these areas.

The ASUS Zenbook Pro 15 has a better screen than the Lenovo Legion Slim 7 for general use, and engineering and design, while the Lenovo Legion Slim 7 has a better screen for gaming and AI.
The ASUS Zenbook Pro 15 excels in screen quality for general use and engineering tasks due to its high resolution and bright display, enabling sharp text and vivid images, along with wide color coverage that ensures accurate color reproduction for design work. However, its lower refresh rate, while sufficient for day-to-day tasks and professional design software, doesn't provide the smooth visuals preferred in high-paced gaming or 3D rendering. The Lenovo Legion Slim 7 offers a similarly high-resolution and bright screen which is good for everyday tasks and design work, but again, its refresh rate falls short for gaming and 3D content, where smoother frame transitions are essential.

Allen Ngo | May 2022
"The ASUS Zenbook Pro 15 offers a strong CPU, chassis, and display. One of the most popular 15.6-inch prosumer or multimedia laptops out there is the Dell XPS 15. Thus, comparisons between it and the Asus Zenbook Pro 15 are inevitable. Asus has a couple of tricks up its sleeve that XPS users are still missing out on including 1080p OLED and an AMD Ryzen CPU which help separate the Zenbook Pro 15 from the XPS 15. It also integrates a numpad and a few more port options albeit at the cost of a larger chassis size."

"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."
