The ASUS TUF Dash 15 generally costs less and has a robust build, making it suitable for gaming, but it's heavier and thicker, which affects portability. Its screen is less bright and with lower color coverage compared to the Lenovo Legion Slim 7, which might matter for tasks like photo editing. The Lenovo Legion Slim 7 offers better color accuracy and a slightly better portability score due to its slim design. If you prioritize performance for 3D rendering, machine learning, or engineering tasks, the Legion Slim 7 might be a better choice despite its higher price, as it scores marginally higher in engineering use.

The Lenovo Legion Slim 7 has a better screen than the ASUS TUF Dash 15 for general use, gaming and AI, and engineering and design.
The ASUS TUF Dash 15 and Lenovo Legion Slim 7 feature panels with sufficient resolution and brightness making them suitable for general use tasks like web browsing and video streaming. Their displays cover a broad range of colors, which is crucial for engineering and design work requiring color accuracy. However, for gaming and 3D applications where smooth motion is key, the lower refresh rates of these laptops' screens can lead to less fluid visual experiences compared to models with higher refresh rates.
The Lenovo Legion Slim 7 15.6" and ASUS TUF Dash 15 are both good for general use.
The ASUS TUF Dash 15 offers strong performance for general use with its Intel CPU and ample RAM, coupled with a quality IPS screen and a decent battery life, making it a solid choice for everyday tasks, though its portability is slightly less than its competitor due to being just a bit heavier.

How the ASUS TUF Dash 15 and the Lenovo Legion Slim 7 15.6" 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 7 is a slim Legion notebook that is just as excellent with Nvidia & Intel. However, the Legion Slim 7i slightly sullied by lacklustre battery life. You get a slim aluminium chassis, great input devices, decent port selection, fast high-quality WQXGA display and great performance. Supporting Thunderbolt 4 is one advantage of the Intel/Nvidia model tested in this review. Moreover, this variant has slightly higher CPU performance as well as better GPU performance in certain applications (e.g. CUDA-based apps). The Lenovo Legion S7i is thin, premium and performant – but less efficient than its AMD counterpart."
