The ASUS ROG Strix G15 is usually more costly than the Lenovo Slim 7 16 because it's aimed at gamers and people needing high performance for tasks like video editing or 3D modeling, offering robust graphics and processing power. However, it's heavier and has shorter battery life, which can impact portability. On the other hand, the Lenovo Slim 7 16 is lighter and has better battery life, making it more suitable for everyday use, traveling, and office work. If you prioritize performance for demanding applications and can handle less portability, go for the ASUS. If you're looking for a balance of performance, battery life, and ease of carrying, the Lenovo might be the better option. Give Feedback

Marius Schell | February 2021
"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."

"At $1,011, the Lenovo IdeaPad Slim 7 Pro is a real bargain among full-sized laptops, with a handsome 16-inch, 16:10 aspect ratio touch screen, a speedy CPU, a comfortable keyboard, ample memory, and a roomy solid-state drive. It's not a blazing gaming rig or mobile workstation, but it doesn't pretend to be. Its biggest negative is that it may be hard to find—during our review, it sold out and was marked "Temporarily Unavailable" on Lenovo's site."
