The ASUS ROG Strix G15 is better for intensive gaming and 3D or machine learning tasks due to its powerful graphics card and high refresh rate screen, but it's heavier and has a shorter battery life, making it less portable than the Lenovo ThinkPad Z13. On the other hand, the Lenovo ThinkPad Z13 is lighter, has a longer battery life, and a higher resolution touchscreen with a 16:10 aspect ratio, which can be better for productivity and general use. The ThinkPad also costs less but isn't as suited for high-performance tasks like gaming or 3D rendering as the ASUS. Give Feedback

How the ASUS ROG Strix G15 and the Lenovo ThinkPad Z13 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."
"In the premium ultraportable space, the Lenovo ThinkPad Z13 competes with the best of the best, and still manages to shine. The design is an impressive departure from the bland bare-metal laptop that's become so popular in recent years, and the AMD-powered system has performance that's just as impressive. It's a stark alternative to the Intel-based majority, and it stands up well enough to the impressive Apple M2 processor."
