The Lenovo Legion Slim 5i offers better portability due to its lighter weight and is generally more affordable, making it suitable for everyday tasks and gaming on a budget. It has a high-quality screen that is good for general use and engineering tasks, but if you need more power for 3D and machine learning applications, the MSI Stealth GS77, while more expensive and heavier, boasts a larger screen, better build quality, and higher performance output ideal for intensive gaming and professional engineering work. However, the Lenovo might have a better battery life for typical usage. Choose the MSI if high performance and screen size are priorities and budget is less of a concern; opt for Lenovo if you seek a balance between cost, performance, and portability. Give Feedback

Although they have very similar scores, PerfectRec considers MSI Stealth GS77 to be very good for general use, while the Lenovo Legion Slim 5i is good.
The MSI Stealth GS77 edges out the Lenovo Legion Slim 5i for general use due to its larger screen, more memory, and slightly higher quality display; however, it comes at the cost of being less portable and heavier. Both laptops come with significant storage and competent CPUs, but the Stealth GS77's additional memory and superior screen outweigh the Slim 5i's advantages in portability and weight for overall general use.

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."

"The MSI Stealth GS77 is better than the GS76... mostly. The GS77 is a few steps forward and a few steps back from the GS76. Improvements are numerous including the stronger and more rigid skeleton, higher resolution webcam, larger clickpad, easier serviceability, relatively similar battery runtimes, newer display options, and higher performance at about the same TDP and TGP levels as before. CPU performance is better than expected even when compared to other laptops with Core i7 or Core i9 processors. The newer model feels more substantial than the outgoing one for higher quality impressions as well."
