If you prioritize high-end performance, especially for 3D rendering, engineering tasks, or gaming, the ASUS ROG Flow Z13 is suitable with its advanced processor and dedicated graphics. However, it also comes at a higher price and is less portable than the Dell. On the other hand, the Dell Inspiron 15 3525 is more budget-friendly and offers a larger screen, but its performance is suitable for general use and less demanding engineering tasks, trading off higher power and graphics capabilities for a more accessible price point. Both have similar battery life, but expect the ASUS to be heavier, impacting its portability. Give Feedback

The ASUS ROG Flow Z13 has a better screen than the Dell Inspiron 15 3525 for general use, gaming and AI, engineering and design, software development, and content creation.
The ASUS ROG Flow Z13 likely has a high-resolution display with excellent brightness and a panel type that renders crisp and vibrant images, making it pleasing for everyday tasks and detailed enough for engineering and design work, although its refresh rate may not meet the demanding needs of gamers and professionals working with 3D applications. On the other hand, the Dell Inspiron 15 3525 seems to provide an adequate display with reasonable resolution and acceptable brightness for general use and engineering tasks, but it falls short for gaming and 3D content due to a possibly lower refresh rate and less precise color rendering. While both laptops may serve general and engineering purposes reasonably well, serious gamers and 3D creators would likely find the display's performance lacking compared to specialized gaming laptops with higher refresh rates and better overall screen quality.

Andreas Osthoff | March 2022
"The Asus ROG Flow Z13 is a gaming tablet with powerful Alder Lake i9 CPU. The ROG Flow Z13 impresses with its good cooling. After our review, the impression is predominantly positive. Besides a very fast Alder Lake CPU and stable gaming performance, especially the cooling system is surprisingly effective and quiet. You can use the integrated speakers without any issues while gaming. The 1200p display in the 16:10 format also impresses with good color reproduction and high brightness. Since the battery runtimes aren't particularly long as it is, we wouldn't recommend the optional 4K panel."

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."
