The ASUS ROG Flow X16 is a solid choice if you prioritize a large, high-resolution touchscreen and better overall color coverage, which is useful for content creation and media consumption. Its processor is also more powerful, suited for intensive tasks. However, be aware that the battery life is shorter than the Lenovo Legion Slim 7, and it's a bit heavier, so it's less portable. The Lenovo Legion Slim 7 has a non-touchscreen, lower-resolution display which is still great for general use and offers longer battery life, making it more portable, although its processor isn't as strong as the ASUS', affecting performance for demanding applications. Both have similar graphics capabilities suitable for gaming and are similarly priced, so choose based on your most essential needs: display and processing power or portability and battery longevity.

The ASUS ROG Flow X16 has a better screen than the Lenovo Legion Slim 7 for general use, gaming and AI, engineering and design, software development, and content creation.
The ASUS ROG Flow X16 excels in general use and engineering due to its high-resolution, bright display, and expansive color gamuts, providing crisp visuals and accurate color reproduction crucial for detailed work. However, its lower refresh rate may not deliver the smooth visuals desired for high-paced gaming and 3D rendering. The Lenovo Legion Slim 7 offers good picture quality and color accuracy for both general use and professional design tasks, but like the ASUS, it falls short for gaming and 3D tasks due to a less optimal refresh rate.

How the ASUS ROG Flow X16 and the Lenovo Legion Slim 7 15.6" compare to other laptops
"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."
"The Lenovo Legion Slim 7 is a slim Legion notebook that is just as excellent with Nvidia & Intel. However, the Legion Slim 7i slightly sullied by lacklustre battery life. You get a slim aluminium chassis, great input devices, decent port selection, fast high-quality WQXGA display and great performance. Supporting Thunderbolt 4 is one advantage of the Intel/Nvidia model tested in this review. Moreover, this variant has slightly higher CPU performance as well as better GPU performance in certain applications (e.g. CUDA-based apps). The Lenovo Legion S7i is thin, premium and performant – but less efficient than its AMD counterpart."
