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."

"The LG Gram 16 is a lightweight device with stability issues. The LG Gram 16Z90Q with a Core i7-1260P is made with portability in mind and places less of a focus on users with high demands on performance. The compact and light chassis is particularly practical when you are on the go. The device is not only comfortably small and lightweight, it also boasts a great battery life. When connected to mains, on the other hand, the 16-inch device is rather disappointing. The standard cooling mode causes extreme volatility in terms of CPU, SSD and iGPU performance. The meager stability of the chassis may also put off some potential buyers."
