If you need a laptop that is more affordable and offers longer battery life for general use, the Lenovo Slim 7 might suit you – it is also lighter for portability. On the other hand, the MSI Stealth GS66, although more expensive, provides superior performance for 3D, machine learning, and gaming tasks, with a much higher refresh rate for smoother visuals. Both have similar storage and memory but expect a tradeoff between the Lenovo's better screen resolution and aspect ratio against the MSI's higher performance graphics card. Consider the Lenovo for regular use and the MSI if you need a powerful laptop for specialized tasks like gaming or engineering applications. Give Feedback

The MSI Stealth GS66 is very good for engineering and design, while the Lenovo Slim 7 16 is good.
The MSI Stealth GS66 edges out the Lenovo Slim 7 16 in engineering and design thanks to its more powerful Intel processor and superior Nvidia RTX GPU, making it very suitable for demanding tasks like 3D modeling and computational simulations. The Lenovo, while still providing a solid CPU and GPU, offers a higher resolution screen, which is beneficial for detailed design work, and it has a slight edge in battery life and portability, but these factors are secondary to raw performance in engineering applications.

Eric Grevstad | March 2022
"At $1,011, the Lenovo IdeaPad Slim 7 Pro is a real bargain among full-sized laptops, with a handsome 16-inch, 16:10 aspect ratio touch screen, a speedy CPU, a comfortable keyboard, ample memory, and a roomy solid-state drive. It's not a blazing gaming rig or mobile workstation, but it doesn't pretend to be. Its biggest negative is that it may be hard to find—during our review, it sold out and was marked "Temporarily Unavailable" on Lenovo's site."

"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."
