The ASUS ROG Flow Z13 has a better screen than the Lenovo Legion Slim 5i for general use, gaming and AI, engineering and design, and software development.
The ASUS ROG Flow Z13 offers a high-resolution display with vibrant colors, crucial for detailed tasks in engineering and design where accurate color representation is key, but its lower refresh rate may not be optimal for the fast-paced visuals required in gaming and 3D applications.

"The Asus ROG Flow Z13 is a gaming tablet with powerful Alder Lake i9 CPU. The ROG Flow Z13 impresses with its good cooling. After our review, the impression is predominantly positive. Besides a very fast Alder Lake CPU and stable gaming performance, especially the cooling system is surprisingly effective and quiet. You can use the integrated speakers without any issues while gaming. The 1200p display in the 16:10 format also impresses with good color reproduction and high brightness. Since the battery runtimes aren't particularly long as it is, we wouldn't recommend the optional 4K panel."

"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."
