The Lenovo Legion Slim 5i offers superior performance, making it well-suited for intensive engineering tasks and gaming due to its advanced processor and powerful graphics card. However, it comes at a higher price point and is slightly heavier, which impacts portability. On the other hand, the MSI GF63 Thin is more affordable and lighter, appealing for general use and offering decent performance for everyday tasks. Its lower hardware capabilities, though, mean it won't handle demanding applications or games as well as the Legion Slim 5i. Give Feedback

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."

"If you leave aside the meagre port selection (no card reader, no DisplayPort, no Thunderbolt 3 or USB 3.1 Gen2), the fan control that could be improved (idle mode!) and the relatively dark and slow display, the MSI GF63 Thin 9SC does not have any major weaknesses. The 15-inch gamer is compact, has a low weight and offers a good price-to-performance ratio, which should please gamers that are looking for both a portable and an affordable gaming notebook. Input devices, battery life, case quality and performance are all appropriate for this purchase price."
