The Lenovo Legion Slim 7 16" is very good for gaming and AI, while the ASUS ROG Flow X16 is good.
The ASUS ROG Flow X16 offers solid gaming and 3D capabilities with its Nvidia RTX 3060 graphics card and a 165Hz screen refresh rate, but the Lenovo Legion Slim 7 16" steps up the game with a more powerful Nvidia RTX 4060 GPU and a higher 240Hz refresh rate, making it very well-suited for more demanding gaming and 3D applications. Both laptops have comparable CPUs and high-quality screens, although these features are somewhat less critical to gaming performance than the GPU and refresh rate.

The Lenovo Legion Slim 7 has a better screen than the ASUS ROG Flow X16 for gaming and AI, content creation, and software development.
For general use, both the ASUS ROG Flow X16 and Lenovo Legion Slim 7 16" offer high-resolution displays with great color accuracy and brightness, which makes text sharp and media vibrant for activities like browsing, streaming, and document work. In engineering and design, their wide color gamuts cover a significant range of the DCI-P3 and Adobe RGB spectra, ensuring that professionals can see accurate colors and subtle gradients crucial for detailed work. However, for gaming and 3D, the lower refresh rates on these laptops may lead to less fluid motion and responsiveness compared to specialized gaming laptops that tend to prioritize higher refresh rates which are essential for a smoother visual experience in fast-paced games and 3D applications.

How the ASUS ROG Flow X16 and the Lenovo Legion Slim 7 16" 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."
