The ASUS ROG Strix G15 has a slightly lower price, excellent for general use and really good for gaming, but with moderate battery life. It's also fairly portable with a solid build and good heat management. The Lenovo Legion 7 is a bit pricier but offers superior performance for 3D tasks, machine learning, and engineering, with a higher resolution and brighter screen that displays colors more accurately. It has a bigger battery, but due to its larger screen and more powerful components, it's heavier and less portable. Both have ample storage, decent keyboards, and are equipped for intensive gaming.

The Lenovo Legion 7 has a better screen than the ASUS ROG Strix G15 for general use, gaming and AI, engineering and design, content creation, and software development.
The ASUS ROG Strix G15 and Lenovo Legion 7 both have high-resolution, bright displays with panel types that enhance color accuracy and viewing angles, making them excellent for general use and detailed engineering work which requires precision in color representation. Both laptops cover a wide range of color gamuts, ensuring that designers see accurate colors while working on projects that demand a fidelity in color reproduction, like photo editing and graphical design. However, both laptops fall short for 3D gaming because they have lower refresh rates, which means less fluid motion and slower response times, aspects crucial for a smooth gaming experience.

How the ASUS ROG Strix G15 and the Lenovo Legion 7 compare to other laptops
"The ASUS ROG Strix G15 is a successful high-performance 15-inch laptop. The Asus ROG Strix impresses with an elaborate design and fast hardware. The latter can unleash its potential well in the large 15-inch case and achieve a decent performance boost compared to the previous generation. Especially the stunning 300 Hz display as well as the RTX 3070 and its generous TDP give gamers their money's worth. Asus didn't neglect seemingly small details, either, such as the keyboard and the maintenance options. The ROG Strix G15 offers a lot of pure performance and excellent workmanship in a 15-inch format, but connectivity leaves something to be desired."
"The Lenovo Legion 7 is a fast 16-inch gamer with 165 Hz display. The new Lenovo Legion 7 is a very good gaming notebook that, despite its comparatively compact compact 16-inch case, does not have to do without the most powerful components. Thanks to good cooling, no compromises are made in terms of performance. Both the Core i9-12900HX and the GeForce RTX 3080 Ti perform at a very high level."
