Choosing between the ASUS ROG Zephyrus G15 and the Lenovo Legion 5 Pro depends on your preferences and needs. The ASUS offers a great balance between performance and portability with a better battery life, making it suitable for on-the-go use, and it's generally less expensive. On the other hand, the Lenovo has a slightly larger screen with a different aspect ratio, newer CPU and graphics which can be better for gaming and engineering tasks but at the expense of battery life and higher cost. Both laptops have similar storage and RAM, ensuring robust performance for general use as well as demanding tasks like 3D rendering and machine learning. If you frequently travel and need longer battery life, consider the ASUS. However, if you prioritize gaming or intensive tasks and don't mind shorter battery life and extra weight, the Lenovo might be the better option. Give Feedback

The ASUS ROG Zephyrus G15 and Lenovo Legion Pro 5 are both good for general use.
The ASUS ROG Zephyrus G15 boasts a more powerful CPU and longer battery life, making it exceptional for an assortment of tasks, while its lighter weight and superior screen quality offer added portability and better viewing experience; this explains its very good rating for general use. The Lenovo Legion 5 Pro, while also satisfactorily equipped for general use tasks with similar RAM and storage capabilities, falls short in battery life and weighs more, which could limit its ease of transport despite its recent release with a somewhat improved processor and better keyboard.

Florian Glaser | February 2021
"As long as you're aware of the fact that the GeForce RTX 3080 laptop version can only unfold its potential to a limited extent due to Asus's low TDP setting and that it can be slower than a fast RTX 3070 laptop, the ROG Zephyrus G15 GA503Q cuts a fine figure. One of the biggest highlights turns out to be the WQHD panel, since it attracts customers with 165 Hz, relatively fast response times, FreeSync, and good color-space coverage. Other selling points are the surprisingly rich sound, the long battery life, and the sleek design. In terms of looks, the white edition stands out nicely from the competition."

"It doesn't quite match its Legion Pro 7i sibling as an Editors' Choice winner, but Lenovo's AMD-powered Legion Pro 5 Gen 8 is a stylish, well-built gaming laptop with solid performance at both 1080p and its sharper native resolution. It's cheaper than some comparably equipped machines and better than some similarly priced ones. That's a recipe for success, even without its frequent availability of discounts or sales. A brighter screen and longer battery life would be nice, but even as is the Legion Pro 5 earns a solid recommendation."
