If you prioritize gaming, 3D work, and machine learning tasks, and don't mind less portability and a heavier device, the ASUS ROG Strix G15 is well-suited for these purposes with its powerful processor and dedicated graphics card. However, if you prefer a lighter, more portable laptop for general use, and value features like a touchscreen and better battery life, the HP Spectre x360 may be the better choice, especially if you're also considering a lower price and a more premium business look. Keep in mind, the Spectre's integrated graphics are not as powerful for demanding tasks like gaming or 3D rendering. 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."

"As we said, Lenovo's Yoga 9i is a tough competitor to the Spectre with an equally admirable OLED display. We're sad that neither of them has an HDMI port nor a niche or slot to hold the stylus, though the HP wins points for its bundled mini docking station and magnetically attached pen. Your choice will come down to screen shape—and in our eyes, just as seeing an OLED screen spoils you for an IPS panel, enjoying a tall 3:2 display spoils you for a more conventional view. The HP Spectre x360 13.5 is our new favorite 2-in-1."
