The ASUS Zenbook Pro 15, released in late 2021, offers an OLED screen and a slightly lighter build for increased portability, favoring those who prioritize a high-quality display and mobility along with mid-range performance at a somewhat higher price. In contrast, the Lenovo Legion Slim 5, brought to market in mid-2023, generally costs less and presents a newer processor and graphics card, potentially better for gaming and demanding tasks. It has an IPS screen with a higher refresh rate, suitable if you value faster screen response for gaming or video editing, though it comes at the expense of slightly heavier weight. Give Feedback

The ASUS Zenbook Pro 15 has a better screen than the Lenovo Legion Slim 5 for general use, and engineering and design, while the Lenovo Legion Slim 5 has a better screen for gaming and AI.
The ASUS Zenbook Pro 15 excels in screen quality for general use and engineering tasks due to its high-resolution display and superior brightness, which enhances visibility and clarity, along with an expansive color gamut that ensures accurate color representation, important for design work. However, its lower refresh rate makes it less ideal for gaming and 3D applications where smoother motion is crucial. The Lenovo Legion Slim 5 also offers a good display for general use and precision tasks, with adequate resolution and brightness, but like the ASUS, its refresh rate does not meet the higher standards required for the best gaming or 3D modeling experience.

"The ASUS Zenbook Pro 15 offers a strong CPU, chassis, and display. One of the most popular 15.6-inch prosumer or multimedia laptops out there is the Dell XPS 15. Thus, comparisons between it and the Asus Zenbook Pro 15 are inevitable. Asus has a couple of tricks up its sleeve that XPS users are still missing out on including 1080p OLED and an AMD Ryzen CPU which help separate the Zenbook Pro 15 from the XPS 15. It also integrates a numpad and a few more port options albeit at the cost of a larger chassis size."

"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."
