The Lenovo IdeaPad Slim 7i Pro has a better screen than the MSI Stealth GS66 for general use, and engineering and design, while the MSI Stealth GS66 has a better screen for gaming and AI, and software development.
The Lenovo IdeaPad Slim 7i Pro boasts a high-resolution display with impressive brightness and color coverage, making it crisp and vibrant for general use and color-sensitive engineering tasks, but its typical refresh rate is a drawback for 3D work, where smoother visuals are key. On the other hand, the MSI Stealth GS66 has a display that balances good brightness and resolution for everyday tasks and professional design work, but similarly lacks a high refresh rate, which compromises its ability to produce the fluid motion desired in gaming and 3D applications. Neither laptop is ideal for 3D and gaming because a superior refresh rate is essential for those fields to avoid motion blur and provide a more immersive experience.

Allen Ngo | October 2021
"The main selling point of the IdeaPad Slim 7i Pro versus a regular IdeaPad Slim 7 is its faster Core H-series CPU. In reality, the Core i7-11370H is only marginally faster than the U-series Core i7-1165G7 to the point where most users are not likely to notice the benefits. The slight performance uptick comes at the cost of slightly higher power consumption as well meaning owners will have to deal with potentially warmer temperatures or louder fans to compensate. Unless if you happen to be a power user, then the regular non-Pro model will be more than enough. Once you go 90 Hz, you can't go back."

"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."
