If you value a vibrant display and casual use or content creation, the ASUS Vivobook S 15 OLED offers a brilliant screen and is generally more affordable, albeit with modest performance. The MSI Stealth GS66, on the other hand, prioritizes high-end performance suitable for 3D rendering, machine learning, and gaming, yet this comes at a higher cost, added weight, and often shorter battery life. Choose the ASUS for everyday tasks and some light creative work, or opt for the MSI if you need top-tier power and are involved in demanding engineering tasks or gaming, keeping in mind the tradeoffs in cost and portability.

How the ASUS Vivobook S 15 OLED and the MSI Stealth GS66 compare to other laptops
"The Asus Vivobook S 15 OLED excels as a capable work machine at an affordable price. It offers commendable performance, thanks to its 12th Gen Intel chip, delivers quality on-screen entertainment with its 15.6-inch OLED display, and can (kind of) get you through a full day of work. Oh, and its special Asus Antibacterial Guard is a nice touch for those who like a clean laptop."
"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."
