The ASUS TUF Dash 15 offers a sturdy build and is tailored more towards gaming, with features like a high refresh rate screen and dedicated graphics. It's also less expensive than the Lenovo option, but with a slightly heavier build and less impressive screen resolution. The Lenovo Legion Slim 7 16", on the other hand, packs a punch with a more advanced graphics card, larger higher-resolution and brighter screen, and greater battery capacity, making it ideal for engineering and demanding graphical tasks. While it's more portable due to its slimmer design, it comes at a higher price point. Choose the ASUS if affordability and a gaming appearance are key, or the Lenovo for higher-end productivity and premium features with a subtler design. Give Feedback

The Lenovo Legion Slim 7 has a better screen than the ASUS TUF Dash 15 for general use, gaming and AI, engineering and design, content creation, and software development.
If you prioritize vibrant displays and crisp visuals for tasks like document editing, web browsing, and media consumption, both the ASUS TUF Dash 15 and Lenovo Legion Slim 7 offer pleasing screen qualities with good resolution and brightness levels that enhance general use. For engineering and design work where accurate color reproduction is crucial, the Lenovo surpasses the ASUS as it likely covers a wider range of color spectra such as DCI-P3 and Adobe RGB, essential for creating and editing visual content. However, for gaming and 3D applications where fast-paced motion is the norm, neither model is ideal due to their lower refresh rates, despite having satisfactory resolution and panel types for less demanding tasks.

"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."
