The MSI GP66 Leopard generally offers robust performance for gaming and general tasks at a lower price, with good cooling and a high-refresh-rate display, making it well-suited for gamers and users with demanding software applications. In contrast, the MSI Stealth 18 AI Studio is tailored for creators and professionals who require a superior display for color-critical work, stronger graphics processing for tasks like video editing and 3D rendering, and a more portable design. However, these features come at a higher cost, and you may find the battery life is shorter due to the more powerful components. Choose the Leopard if price and gaming are priorities, or the Stealth if mobility and creative work are paramount. Give Feedback

Christian Hintze | December 2021
"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."
