Choosing between the Lenovo Legion Slim 7 and the MSI GP66 Leopard involves considering portability, battery life, and performance. The Lenovo offers greater battery life and portability, making it suitable for on-the-go use and prolonged sessions away from a power source. It also has a higher-quality keyboard, which can be important for typing comfort over long periods. However, the MSI has a more powerful graphics card, delivering better performance for activities such as 3D rendering, machine learning, and intensive gaming. Despite its superior performance, note that it is heavier, which may impact comfort for mobile users, and it has a shorter battery life, so frequent access to power may be necessary. The MSI is also likely to be somewhat more expensive, so if budget is a concern, the Lenovo may be the more cost-effective option. Give Feedback

"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 GP66 Leopard is a good budget high-performance gamer. The MSI also does a lot right outside of the pure performance despite it's low price. For example, the adaptive cooling system really surprised us positively, even in Extreme Performance Mode. And the display is not a budget panel either, but at least outshines the competition in terms of brightness. Of course, you also have to accept a few compromises in this price category. These include the Leopard's poor battery runtimes and the less than optimal build quality, which is also noticeable in the more complicated maintenance."
