Understanding your preference for a less expensive option like the Lenovo Legion Slim 5, consider that it offers a decent balance of performance thanks to its AMD Ryzen processor and Nvidia RTX graphics, which are well-suited for general use and some gaming. The Lenovo also has respectable battery life and a 16:10 display which is great for productivity tasks. In contrast, the MSI Stealth GS66, while more expensive, features a high-refresh-rate screen for smooth visuals in gaming and a more powerful Intel processor paired with an Nvidia RTX 3070 Ti, excellent for demanding tasks and intensive work like 3D modeling or machine learning. It's also quite portable due to its lighter weight. So, if your primary concerns are budget and a solid all-around performance, the Lenovo is a strong option; if you require high performance for gaming or professional applications and value portability, and are willing to invest more, the MSI may justify its cost.

PCMag

Mark Knapp | August 2023
"The Lenovo Legion Slim 5 Gen 8 acknowledges that a gaming laptop doesn’t have to be as thick as possible and can still ensure adequate cooling when the muscles need flexing. To this end, in the Slim 5 Gen 8, it finds a neat balance of refined, trimmed-down design that still lets its internals cruise (even above their max power ratings). Lenovo then added in some high-end build quality with an altogether excellent keyboard that’s useful for both work and play."

Florian Glaser | February 2022
"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."
