When choosing between the Lenovo LOQ 15 and the Razer Book 13, consider your primary needs. If gaming or engineering work is a priority, the Lenovo, with its dedicated RTX graphics, provides higher performance suitable for these tasks. However, the Razer Book, with better battery life and portability due to its lighter weight and smaller screen, may serve you better for general use and travel. The Razer Book's display also features a touchscreen and a higher resolution, which could be beneficial for productivity tasks. Both laptops have similar storage and memory capacities, so your decision should hinge on whether you prioritize performance for intensive tasks or battery life and portability for everyday use.

PCMag
Mark Knapp | August 2023
"Even after a short time with the LOQ 15, you'll find it has a lot going for it, but ultimately it's just "good"—not quite a star. The performance is respectable for the hardware it’s running, but Lenovo had to make some design sacrifices to trim the price. One of the better aspects is the keyboard, making it one of the better low-cost gaming laptops to actually put your hands on."

Allen Ngo | December 2020
"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."
