If your priority is gaming or graphics-intensive tasks such as video editing or 3D rendering, the MSI Stealth GS66, with its powerful graphics card and high-performance processor, would be a better fit, though it comes at a higher cost and has lower battery life. On the other hand, if you're looking for a laptop that is more affordable, offers longer battery life, and is adequate for general use, media consumption, and lighter productivity tasks, consider the Lenovo IdeaPad Slim 5i. Both have the same amount of storage and memory, but the Lenovo is slightly lighter and therefore more portable, whereas the MSI has superior build quality, heat management, and a higher refresh-rate display, which is advantageous for fast-paced games.

The MSI Stealth GS66 is good for gaming and AI, while the Lenovo IdeaPad Slim 5i is only fair.
The MSI Stealth GS66 outperforms the Lenovo IdeaPad Slim 5i in gaming and 3D because it includes a more powerful Nvidia RTX 3070 Ti GPU and boasts a higher screen refresh rate of 360Hz compared to the IdeaPad's integrated Intel Iris Xe graphics and 60Hz refresh rate.

The MSI Stealth GS66 has a better screen than the Lenovo IdeaPad Slim 5i for general use, gaming and AI, engineering and design, and software development.
The Lenovo IdeaPad Slim 5i offers satisfactory display characteristics like resolution and brightness for everyday tasks, but its coverage of professional color spaces may not be ideal for precision tasks like engineering and design.

"The device is made for average work loads and if your work has a lot to do with online browsing, using apps that are not power-hungry and streaming videos. The looks are really good and the device in itself is not a heavy one. And with Intel 11th-gen Core processor, you might sail through most of your work without complaints."

"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."
