The ASUS ROG Strix G15 is better suited for intensive gaming and engineering tasks due to its higher performance components, but it is heavier and has shorter battery life compared to the Dell Inspiron 14 7420, which offers better portability and longer battery life, making it a better option for general use and everyday tasks. The Dell Inspiron also has a higher resolution touchscreen display, which is preferable if you need touch capabilities or work frequently with documents and media. However, if gaming or resource-heavy applications are a priority, the ASUS with its dedicated graphics card and robust processor outperforms the Dell. Give Feedback

Marius Schell | February 2021
"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."

"Notable qualities of the Inspiron 7420 2-in-1 include the 16:10 aspect ratio, strong hinges, 12th gen Intel CPU with optional GeForce MX graphics, and easy serviceability. Such features would typically cost hundreds of dollars more on higher-end alternatives from competing manufacturers. The value proposition is therefore relatively high for users looking to maximize bang for the buck."
