The Lenovo Legion Slim 5i is a more suitable option for gaming and engineering tasks due to its higher performance graphics card, and is also a good pick if you need more built-in storage. However, it's heavier and has a shorter battery life compared to the Razer Book 13. Thus, the Razer Book 13 is more portable and offers longer battery life, making it ideal for general use and tasks that do not demand high-end graphics, such as document editing or browsing. Additionally, if you value a touchscreen for easier navigation or creative tasks, the Razer Book 13 includes one. Give Feedback

The Lenovo Legion Slim 5i is very good for engineering and design, while the Razer Book 13 is good.
The Lenovo Legion Slim 5i excels in engineering and design use due to its more powerful CPU and GPU, which improve performance for resource-intensive tasks, and a higher resolution screen that provides better detail and workspace, though it sacrifices some portability and has a shorter battery life compared to the Razer Book 13. The Razer Book 13, while still suitable for engineering and design, offers greater portability, longer battery life, and a high-quality screen, yet its performance is less formidable due to a less powerful CPU and integrated GPU which may not handle demanding applications as effectively.

For general use, both the Lenovo Legion Slim 5i and the Razer Book 13 provide screens that are bright, clear, and have high resolution, making them suitable for everyday tasks like browsing and video streaming.

Mark Knapp | August 2023
"The Lenovo Legion Slim 5 Gen 8 acknowledges that a gaming laptop doesn’t have to be as thick as possible and can still ensure adequate cooling when the muscles need flexing. To this end, in the Slim 5 Gen 8, it finds a neat balance of refined, trimmed-down design that still lets its internals cruise (even above their max power ratings). Lenovo then added in some high-end build quality with an altogether excellent keyboard that’s useful for both work and play."

"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."
