The Lenovo Legion Slim 7 has a better screen than the ASUS ROG Strix Scar 15 for general use, gaming and AI, engineering and design, content creation, and software development.
For general use, the Lenovo Legion Slim 7's higher resolution and brightness offer crisper visuals and easier viewing in various lighting conditions, while the ASUS ROG Strix Scar 15 may have a lower resolution or brightness, reducing visual clarity and comfort. In engineering and design, the Legion Slim 7 provides superior color accuracy with wider color gamuts, ensuring more precise color representation which is critical for professional work, whereas the Strix Scar 15's color gamuts may not be as broad, affecting the fidelity of color-sensitive tasks. However, for gaming and 3D tasks, the Strix Scar 15 falls short due to a lower refresh rate, which results in less fluid motion, making the Legion Slim 7 a slightly better option despite its own limitations in refresh rate compared to specialized gaming models.

How the ASUS ROG Strix Scar 15 and the Lenovo Legion Slim 7 16" compare to other laptops
"Asus continues to refine the ROG Strix Scar lineup with new upgrades. The Asus ROG Strix Scar 15 offers almost everything you would expect from a gaming laptop at this price. The build quality is great, connectivity options are decent, and there is enough scope for internal upgrades as well. Asus reverts to membrane switches for the keyboard — though not as "clickety" as the opto-mechanical ones we saw with last year's model, they still make for a decent typing and gaming experience. The lack of biometrics in any form is a downer."
"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."
