The ASUS Zenbook Flip S13 is an upper midrange option with a high-resolution touchscreen, making it suitable for daily use and creative tasks with stylus support, while offering strong build quality and portability due to its light weight. In contrast, the Lenovo Legion Slim 5i, a lower midrange priced laptop, excels in 3D rendering and machine learning performance due to its powerful dedicated Nvidia GPU, but sacrifices a bit on battery life and portability with its larger screen size and higher weight. If top-notch gaming, 3D, or engineering work is a priority and you're okay with a heavier device, the Lenovo is a solid choice; otherwise, for more general use, better portability, and touchscreen features, the ASUS could be the better option.

The ASUS Zenbook Flip S13 has a better screen than the Lenovo Legion Slim 5i for general use, and engineering and design, while the Lenovo Legion Slim 5i has a better screen for gaming and AI, and software development.
For general use, the ASUS Zenbook's superior resolution and brightness make it stand out, while the Lenovo Legion Slim's decent screen quality will suffice without quite matching the Zenbook's clarity and vibrancy. When it comes to engineering and design tasks, the ASUS Zenbook excels due to its wider color gamut coverage, essential for accuracy in color-critical work, whereas the Lenovo Legion Slim, with a good color range, may not satisfy professionals who need the highest level of color fidelity. However, for gaming and 3D purposes, both laptops fall short due to lower refresh rates, which are crucial for smooth visuals, despite having the resolution and panel types that partially meet the requirements for these activities.

How the ASUS Zenbook Flip S13 and the Lenovo Legion Slim 5i compare to other laptops
"The Asus Zenbook S 13 Flip is an ultra-sleek 2-in-1 convertible. A gorgeous OLED screen and lightweight magnesium chassis make this convertible a traveller’s dream. Its SSD isn’t fast, but it won’t hold you back in everyday use. Its battery life also isn’t class leading, but it’s hardly off the pace. Overall, the Zenbook S 13 Flip OLED holds its head high in the premium convertible category and is a smaller alternative to the Spectre x360 13.5 and the Yoga 9i Gen 7."
"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."
