The ASUS ROG Strix G18 is more suitable for intensive engineering tasks, 3D rendering, and machine learning due to its superior main processor and graphics card. However, it is heavier and has a larger screen, making it less portable than the ASUS ROG Strix Scar 15. The Scar 15, while offering slightly lower performance in these areas, is more portable and has a higher refresh rate display, which might be preferable for fast-paced gaming. Both laptops have substantial battery capacity and are similarly priced, but if portability is crucial and the slight dip in performance is acceptable, the Scar 15 could be a better choice.

The ASUS ROG Strix G18 has a better screen than the ASUS ROG Strix Scar 15 for general use, gaming and AI, engineering and design, software development, and content creation.
For general use, the ASUS ROG Strix G18 outshines the Scar 15 due to its higher resolution and brighter display, which makes viewing text and images clearer and more vibrant, enhancing everyday tasks like browsing and video streaming. In engineering and design work, the ROG Strix G18's superior color accuracy, with broader color gamuts, ensures that professionals see precise hues and contrasts, vital for tasks requiring color fidelity. However, for gaming and 3D applications, the lower refresh rate of the G18's display can lead to less fluid motion and responsiveness compared to screens designed specifically for these tasks, which may hinder fast-paced visual experiences.

Although they have very similar scores, PerfectRec considers ASUS ROG Strix G18 to be very good for general use, while the ASUS ROG Strix Scar 15 is good.
The ASUS ROG Strix G18 is preferred for general use due to its superior screen with higher pixel density, brightness, and color accuracy, paired with the latest Intel i9 CPU which excels in multitasking and performance. Conversely, the ASUS ROG Strix Scar 15 has a more portable design with less weight, but its screen has lower resolution and color coverage, and an older generation CPU, which, while still powerful, may not handle intensive tasks as efficiently as the G18.

The ASUS ROG Strix G18 and ASUS ROG Strix Scar 15 are both very good for gaming and AI.
The ASUS ROG Strix G18 is highly suitable for gaming and 3D due to its advanced Nvidia RTX 4070 GPU and high 240 screen refresh rate, while the ASUS ROG Strix Scar 15 also stands out in these areas with a strong Nvidia RTX 3070 Ti GPU and an even higher 300 refresh rate; although the Scar 15's lower screen pixel density indicates marginally less sharp images when compared to the G18.

The ASUS ROG Strix G18 and ASUS ROG Strix Scar 15 are both very good for engineering and design.
The ASUS ROG Strix G18, with its top-tier Intel i9 processor, ample RAM, advanced NVIDIA RTX GPU, and large high-resolution screen, is an excellent choice for demanding engineering and design work that requires strong performance and detailed visuals. Although both laptops feature quality keyboards and speakers, the ASUS ROG Strix Scar 15 is more portable and has a higher refresh rate screen, but its previous-generation CPU and GPU mean it won't handle intensive tasks as effectively as the G18 but will still perform very well in engineering and design scenarios.

"With the ROG Strix G18, Asus has made an almost consistently good debut in the still quite new 18-inch laptop segment. The base unit case shows a few signs of weakness in the area of stability and is something which has an effect on the perceived quality of the input devices (the chassis tends to rattle a bit). Nevertheless, thanks to generous port features (incl. Thunderbolt 4), a striking design, and extensive lighting (keyboard, LED strip on the front), gamers get a fitting gaming platform."

"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."
