If you prioritize longer battery life and a higher-quality screen, the Razer Book 13 will be the better option. It's also more portable due to its smaller size and lighter weight. Additionally, it comes with more RAM, which may make it faster for multitasking and complex tasks. However, the Dell Inspiron 15 is a budget-friendly choice with a larger screen and includes a number pad on the keyboard, which may be beneficial for productivity. The Dell's main processor and GPU are suitable for everyday tasks, but the Razer has better performance for more demanding applications, although neither is ideal for intensive gaming. If affordability is a key concern, the Dell Inspiron would be cost-effective, but if you are willing to spend more for better performance and screen quality in a more compact form, then the Razer Book is a superior option.

The Razer Book 13 and Dell Inspiron 15 3525 are both only fair for gaming and AI.
The Dell Inspiron 15 3525 and the Razer Book 13 are considered fair for gaming and 3D because they both have integrated graphics—Vega 7 in the former and Iris Xe in the latter—which are less capable than dedicated GPUs for demanding graphics tasks, and 60Hz screen refresh rates, which could limit smoothness in fast-paced games compared to higher refresh rates. While both have decent CPUs and screen quality, their primary limitations for gaming and 3D work come from the GPU and refresh rate constraints.

PCMag
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."

"The Razer Book is like an XPS 13, but faster. The Book 13 combines the design philosophy and performance of a Blade Stealth with the 16:10 display of a Dell XPS 13 for an impressive piece of hardware. Office users who want something more stylish than the typical Dell, HP or Lenovo will certainly find themselves drawn to this Razer subnotebook. If your priorities are to have the best-looking and fastest 13-inch laptop in the office over auxiliary features, however, then the Book 13 proudly fulfills that niche."
