The Dell Alienware m15 R7 is very good for engineering and design, while the ASUS ROG Strix G15 is good.
The Dell Alienware m15 R7 is better suited for engineering and design due to its stronger graphics card (Nvidia RTX 3070 Ti), higher resolution screen, and larger battery capacity which are very important for demanding tasks and visual clarity, whereas the ASUS ROG Strix G15, although it has ample storage and a powerful CPU, comes with a less capable graphics card (Nvidia RTX 3050 Ti) and a lower resolution screen. However, the ASUS is lighter and thus more portable, and both have similar RAM, which is a somewhat important factor for multitasking and complex operations.

The Dell Alienware m15 R7 has a better screen than the ASUS ROG Strix G15 for general use, gaming and AI, and engineering and design.
When considering a laptop for general use, the Dell Alienware m15 R7's combination of panel type, high resolution, and brightness contributes to its very good screen quality, offering crisp, clear visuals for daily tasks. For engineering and design work, this same laptop also excels due to its wide color gamuts, ensuring accurate color reproduction which is essential for detailed and color-critical work. However, for gaming and 3D applications where smooth motion is key, both the ASUS ROG Strix G15 and the Dell Alienware m15 R7 fall short due to their lower refresh rates, despite their suitable resolutions and panel types.

How the ASUS ROG Strix G15 and the Dell Alienware m15 R7 compare to other laptops
"The ASUS ROG Strix G15 is a successful high-performance 15-inch laptop. The Asus ROG Strix impresses with an elaborate design and fast hardware. The latter can unleash its potential well in the large 15-inch case and achieve a decent performance boost compared to the previous generation. Especially the stunning 300 Hz display as well as the RTX 3070 and its generous TDP give gamers their money's worth. Asus didn't neglect seemingly small details, either, such as the keyboard and the maintenance options. The ROG Strix G15 offers a lot of pure performance and excellent workmanship in a 15-inch format, but connectivity leaves something to be desired."
"The Alienware M15 offers solid gaming and leading endurance. It makes the most of its CPU and GPU while delivering stellar battery life for a gaming laptop. Opening the lid presents a full-size keyboard with honeycomb cutouts above it on the deck. An oblong RBG lightning element surrounds the entire rear panel and can be color-synced with the other lights on the laptop. There’s not a lot to dislike about the M15 Its productivity performance lagged in some areas, particularly in the storage benchmark, and it’s a bit heavy. Alienware has a clear winner here with the M15 based on its strong overall performance and endurance."
