"The 2023 Dell XPS 15 is more or less exactly what you'd expect from the company flagship. Its fresh components deliver measurably superior power and longevity, while the machine's premium build and design remain intact. It may not be overly exciting, but XPS loyalists and upgraders should be more than happy."

"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."
