The ASUS Zenbook Pro 15, at a more midrange price, offers a vivid OLED touchscreen and a moderate battery life suitable for general use and light creative tasks. On the other hand, the MSI Stealth GS66, with a higher price tag, provides stronger performance for demanding 3D, machine learning, and gaming tasks, but has a significantly shorter battery life. Both are similarly portable, but the MSI has a higher refresh rate display which is better for fast-paced visuals, albeit without a touchscreen. Give Feedback

"The ASUS Zenbook Pro 15 offers a strong CPU, chassis, and display. One of the most popular 15.6-inch prosumer or multimedia laptops out there is the Dell XPS 15. Thus, comparisons between it and the Asus Zenbook Pro 15 are inevitable. Asus has a couple of tricks up its sleeve that XPS users are still missing out on including 1080p OLED and an AMD Ryzen CPU which help separate the Zenbook Pro 15 from the XPS 15. It also integrates a numpad and a few more port options albeit at the cost of a larger chassis size."

"The MSI Stealth GS66 is powerful enough for QHD. The Core i7-12700H and the GeForce RTX 3070 Ti found in the 12UGS model that we tested run all modern games smoothly in the native QHD resolution. The 15-inch display is very fast with its 240 Hz refresh rate, and it also offers a great color space (almost 100% DCI-P3) on top of that, which should please gamers as well as content creators, although we would have still wished for a higher brightness. Case, input devices, and connectivity (Thunderbolt 4) are at a good level. However, among other things, the GS66 loses points due to the high temperature development in 3D mode and its poor webcam."
