Both laptops feature similar storage and memory capacities, so your decision may also consider the better price point you find for the specific model that meets your balance of needs between portability and performance for intensive tasks.

Benjamin Herzig | November 2022
"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."

"The MSI Pulse GL66 has a lot of potential for improvement. Although the RTX 3060 is only able to use 105 watts, we still liked the gaming performance, particularly since this also makes the Pulse comfortably efficient but not slow by any means. Neither the dark display with its lame response times, nor USB 2.0 or the lack of Thunderbolt will please real gamers. The use of a sticker factory seal, which is at least questionable, also won't inspire any enthusiasm. It is obvious that the laptop is really designed for price-conscious gamers."
