The ASUS ROG Strix G17 is often more expensive, offers better heat management, and is designed for intensive gaming with a high refresh rate display and powerful CPU and GPU, but it's heavier and has a shorter battery life. Meanwhile, the Lenovo Legion Slim 5i is more affordable, lighter, making it more portable, has a longer battery life, and boasts better portability and keyboard quality scores. Both have similar storage, RAM, and high-resolution displays, but expect the ASUS to outperform in demanding tasks at the expense of battery life and portability. Choose the ASUS if gaming and high-performance are your priority or the Lenovo if you prefer portability and longer use off the charger. Give Feedback

The ASUS ROG Strix G17 has a better screen than the Lenovo Legion Slim 5i for general use, gaming and AI, engineering and design, and content creation.
For general use, the ASUS ROG Strix G17's high-resolution display and brightness make it clear and easy to view, whereas the Lenovo Legion Slim 5i, while slightly less bright, still offers a crisp image suitable for everyday tasks. In engineering and design, the ASUS stands out with its wider color coverage, enabling more accurate color representation, but the Lenovo still offers respectable color fidelity that can suffice for less color-critical work. However, for gaming and 3D applications, the ASUS's lower refresh rate puts it at a disadvantage compared to laptops with faster screens, which makes the Lenovo a better match if it had a higher refresh rate, despite its other screen limitations.

"The Asus ROG Strix G17 is an attractive but unbalanced gaming laptop. Its potent AMD Ryzen 9 processor excels in 1080p gaming, but playing at 1440p leaves the middling GeForce RTX 4060 GPU shouldering most of the burden. The display is exceptionally colorful, which is handy for content creators, but since this is a gaming laptop it would be better served with improved HDR capabilities. If battery life isn't a priority, the Strix G17 could serve as a designer by day and a gamer by night."

"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."
