The ASUS ROG Strix G15 offers high performance for 3D rendering, machine learning, and gaming, with a powerful AMD Ryzen 9 processor and Nvidia graphics, but it is less portable than the Dell due to its higher weight and lower battery life. The Dell Inspiron 15 is more affordable, with adequate capability for general use and engineering tasks, offers a touchscreen, and longer battery life, making it more suitable for on-the-go usage. The ASUS is more tailored towards users prioritizing gaming and intensive tasks at a higher cost, while the Dell balances cost with performance for everyday productivity. Give Feedback

"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."

Mark Knapp | January 2023
"Dell's Inspiron 15 (3525) is a peppy-enough and affordable-enough home or remote work machine, but it's not very ambitious; it does little to go beyond the basics. More the concern: It’s readily overshadowed by a number of machines that outperform and outclass it. Even if the Inspiron can get the job done today, its competition has the mettle to keep doing the job tomorrow in a way the Inspiron simply can’t promise. Many of its slightly higher-end rivals have to be on sale (and frequently are) to match it on price, but the Inspiron 15 (3525) is outclassed even by some similarly priced options, making it a difficult recommendation."
