The ASUS ROG Strix G15 is more suitable for gaming and heavy 3D tasks due to its powerful AMD Ryzen 9 processor and Nvidia RTX graphics, but it is heavier and has a shorter battery life, making it less portable than the Dell Inspiron 14 5420. On the other hand, the Dell Inspiron has a higher resolution screen, which is better for general use and professional tasks, a lighter build for improved portability, and longer battery life, but its Intel i7 processor and Nvidia MX graphics are less powerful for intensive gaming and 3D rendering. Both laptops have a backlit keyboard and similar RAM and storage configurations, with the ASUS offering a slightly larger screen, while the Dell offers a better webcam and higher portability.

The ASUS ROG Strix G15 has a better screen than the Dell Inspiron 14 5420 for general use, gaming and AI, engineering and design, and content creation, while the Dell Inspiron 14 5420 has a better screen for content creation.
The ASUS ROG Strix G15's screen offers high resolution and brightness, making it appealing for general use and detailed engineering work, but its lower refresh rate compared to gaming-optimized screens holds it back for gaming and 3D applications. On the other hand, the Dell Inspiron 14 5420, while providing adequate brightness and resolution for general tasks and engineering designs, doesn't stand out in any particular aspect, which limits its performance across various domains, especially for gaming where higher refresh rate is key. Both laptops exhibit screen quality that aligns with different priorities and while neither is ideal for gaming or 3D due to refresh rate limitations, they can handle general use and engineering tasks competently.

How the ASUS ROG Strix G15 and the Dell Inspiron 14 5420 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."
"If laptops were food, then the Dell Inspiron 14 5420 is arguably a Big Mac. There are cheaper and more expensive options, but this arguably represents the baseline of quality and value in the world of mobile computing… something that’s underlined by the attractive $1,279 price tag."
