If you prioritize a more portable and versatile device for general use, the ASUS ROG Flow Z13 with its smaller screen and lighter weight makes sense, plus it has a touchscreen and a higher pixel density for sharper visuals. However, it may cost more, and its battery life doesn't last as long as the Lenovo's. On the other hand, the Lenovo Legion Slim 7 16" offers a larger screen for an immersive experience especially in engineering tasks and 3D applications, a slightly better battery life, and tends to be less expensive. It's more suitable for you if you prefer a bigger display and possibly a bit more power for intense gaming or heavy software use, although it is heavier, impacting its portability. Give Feedback

Andreas Osthoff | March 2022
"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 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."
