The ASUS Zenbook Flip S13 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 Zenbook Flip S13 boasts a high-resolution display with great brightness and color reproduction, making it excellent for everyday tasks and detail-oriented engineering work, but its standard refresh rate makes it less ideal for the fast-paced visuals required in gaming and 3D applications. The Dell Inspiron 15 3525 offers a fair screen that is satisfactory for average daily use and sufficient for basic engineering and design due to its acceptable resolution and color accuracy, but it falls short for gaming and 3D with its lower refresh rate. Both options are less suitable for gaming and 3D work, as high refresh rates are crucial for fluid motion and these laptops don't prioritize that feature.

Charles Jefferies | January 2023
"The Asus Zenbook S 13 Flip is an ultra-sleek 2-in-1 convertible. A gorgeous OLED screen and lightweight magnesium chassis make this convertible a traveller’s dream. Its SSD isn’t fast, but it won’t hold you back in everyday use. Its battery life also isn’t class leading, but it’s hardly off the pace. Overall, the Zenbook S 13 Flip OLED holds its head high in the premium convertible category and is a smaller alternative to the Spectre x360 13.5 and the Yoga 9i Gen 7."

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."
