The ASUS ROG Flow X16 is very good for general use, while the Lenovo IdeaPad Slim 3 is good.
The ASUS ROG Flow X16 stands out for general use due to its more powerful CPU, larger RAM capacity, higher screen resolution and quality, along with its flexibility as a convertible 2-in-1 device, at the cost of a lower battery life than the Lenovo IdeaPad Slim 3. The IdeaPad Slim 3, while less powerful in terms of CPU and RAM, offers greater portability and longer battery life, but with a lower-resolution display and a smaller storage capacity, it's more suitable for less demanding tasks.

The ASUS ROG Flow X16 has a better screen than the Lenovo IdeaPad Slim 3 for general use, gaming and AI, engineering and design, software development, and content creation.
The ASUS ROG Flow X16 likely has a higher resolution and brighter display, making it suitable for general use and engineering where detail and color accuracy are key. Its lower performance in gaming could be due to a lower refresh rate, which is less suitable for fast-paced visuals in games. Conversely, the Lenovo IdeaPad Slim 3, while having adequate resolution and brightness for everyday tasks and some engineering work, falls short for professional design and gaming due to more modest color coverage and refresh rates.

"Above all else, the Asus ROG Flow X16 is one thing - versatile! It is a thin, mobile work device, it's a 2-in-1, tablet, a powerful workstation and even a gaming PC. But something even more surprising: It does all of these things really well without making any big blunders. It's anything but a lazy compromise. Because, despite its compact dimensions and 2-in-1 functionality, the hardware isn't throttled and boasts, at least in turbo mode, above-average performance."
Olivier Martin, Ryan Lim, and John Peroramas | May 2023
"The Lenovo IdeaPad 3i is decent for use as a workstation. Its Intel CPU and integrated graphics can only handle light productivity tasks, not demanding workloads like video editing or 3D graphics. You also can't do any color-critical work because the available displays have a narrow color gamut. It has a good port selection, but its USB-C lacks Thunderbolt 4 support. On the upside, it has a comfortable keyboard and doesn't get hot or loud under load."
