If you prioritize battery life and a more vibrant, high-quality display, the Razer Book 13 may serve you better, and it also offers a slightly larger screen with a touch option. It tends to be more expensive, but it includes more storage space as well. On the other hand, the LG Ultra 13 is lighter and generally more cost-effective, making it a compelling choice if you value portability and savings. However, it might not perform as well as the Razer Book 13 for more demanding tasks like 3D rendering or intensive engineering work due to less powerful graphics capabilities. Both have ample RAM for everyday tasks and sturdy build quality. If you often engage in tasks like video editing or gaming, the Razer might justify its higher cost with its superior display and performance. Give Feedback

The Razer Book 13 has a better screen than the LG Ultra 13 for general use, gaming and AI, engineering and design, content creation, and software development.
For general use, both the LG Ultra and the Razer Book have displays with sufficient resolution and brightness, which makes them suitable for everyday tasks like browsing and video streaming. Engineers and designers would find these laptops appropriate because they offer wide color gamuts, ensuring accurate color representation needed for professional design work. However, they are not ideal for gaming and 3D applications due to their lower refresh rates, which can make fast-paced visuals less smooth compared to screens designed specifically for those purposes.

The Razer Book 13 and LG Ultra 13 are both only fair for gaming and AI.
The LG Ultra 13 and Razer Book 13 laptops have integrated GPUs that are less capable than dedicated gaming GPUs, meaning they can handle light gaming but may struggle with more demanding 3D tasks. Both have standard screen refresh rates, which are suitable for ordinary tasks but less so for high-end gaming that benefits from faster rates; however, the Razer Book 13 slightly edges out with a higher quality display that might offer a better viewing experience despite the same refresh rate limitation.

Although they have very similar scores, PerfectRec considers Razer Book 13 to be good for engineering and design, while the LG Ultra 13 is only fair.
The Razer Book 13 is rated better for engineering and design use mainly because it boasts a more potent Intel i7 processor and superior Intel Iris Xe graphics compared to the AMD Ryzen 7 CPU and Vega 7 graphics of the LG Ultra 13; additionally, the Razer features a higher resolution touchscreen with better screen quality including brightness and contrast. While both laptops offer solid performance with ample RAM, the tradeoff lies in the Razer's slightly heavier build, potentially affecting portability, and a higher-quality keyboard which could be an advantage for extended typing sessions typical in engineering and design tasks.

"The 13.3-inch LG Gram is a fine fit if you need to travel as light as possible for as long as possible without spending a fortune to do it. It might not be particularly sturdy or have an eye-catching design and its webcam is less than ideal, but with its sharp touch display, comfortable backlit keyboard, responsive touchpad and a fingerprint reader for extra security, the Gram makes a respectible everyday laptop for business or school work."

"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."
