The ASUS ROG Flow X13 is a premium option with a high refresh rate touchscreen, making it suitable for intensive gaming and creatives needing precise color representation. Its portability is complemented by a lightweight design, but this comes at a higher cost. Alternatively, the Lenovo Legion Slim 5i offers a better value at a lower price, with a larger screen and a number pad that could appeal to users comfortable with a heavier build for general use, engineering, and gaming, though it lacks a touchscreen and has a lower portability factor. Both have similar storage, RAM, and processing power suitable for demanding tasks. Give Feedback

Although they have very similar scores, PerfectRec considers Lenovo Legion Slim 5i to be very good for gaming and AI, while the ASUS ROG Flow X13 is good.
The Lenovo Legion Slim 5i is preferred for gaming and 3D due to its slightly superior GPU, the Nvidia RTX 4060, which offers better performance over the Asus ROG Flow X13's Nvidia RTX 4070. Both laptops have equal screen refresh rates which are important for smooth visuals in gaming and 3D applications; however, the Legion Slim 5i benefits from a larger 16" screen compared to the Flow X13's 13.4", providing a more immersive experience.

How the ASUS ROG Flow X13 and the Lenovo Legion Slim 5i compare to other laptops
"The Asus ROG Flow X13 is not an off-the-shelf convertible. This quickly becomes clear when you take a closer look at the technical specs. The AMD Ryzen 9 5980HS is a state-of-the-art SoC with 8 cores and 16 threads, which also makes the 2-in-1 interesting as a work device. With 32 GB of RAM and a 1 TB SSD, gamers are also well taken care of. The dedicated Nvidia GeForce GTX 1650 Max-Q fits well into the overall concept and ensures a solid 3D performance. With the eGPU dock, which is equipped with a GeForce RTX 3080, the small convertible transforms into a full-fledged desktop replacement in terms of performance."
"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."
