The ASUS TUF Dash 15 is more portable and offers a balance of performance suitable for engineering, gaming, and general use, also providing good value for its price with solid build and cooling. However, the Lenovo Legion Slim 5i has a higher resolution and more vibrant screen, better suited for creative tasks and detailed work, along with stronger performance in 3D, machine learning, and engineering applications. If your work involves graphics-intensive tasks and you prefer a higher quality display, the Legion Slim 5i may be worth the extra weight and potentially higher price. If portability is key and you need a laptop that's well-rounded for a variety of tasks without the higher screen resolution, the ASUS would serve you well. Give Feedback

How the ASUS TUF Dash 15 and the Lenovo Legion Slim 5i compare to other laptops
"The Asus TUF Dash F15 FX517ZR is a laptop with mobile RTX 3070 and acceptable battery life. The Asus TUF Dash F15 was made for high-performance applications like video editing, rendering, and gaming. The laptop can manage the latter in QHD resolution and at high to maximum settings. However, the focus isn't on maximum performance, but instead, it's about a compromise between performance and portability."
"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."
