The Lenovo Legion Slim 5 has a better screen than the MSI GP66 Leopard for software development, while the MSI GP66 Leopard has a better screen for general use, gaming and AI, and engineering and design.
The Lenovo Legion Slim 5 and MSI GP66 Leopard both offer displays with resolutions and brightness levels that are satisfactory for everyday tasks, contributing to their good screen quality for general use. For engineering and design, their color accuracy and range are significant for professionals, and since both laptops provide decent coverage of color spaces like DCI-P3 and Adobe RGB, they're deemed good for these applications as well.

The Lenovo Legion Slim 5 and MSI GP66 Leopard are both good for general use.
The Lenovo Legion Slim 5 offers a balanced experience for general use, boasting ample memory and storage, a competent AMD Ryzen CPU, and a high-quality IPS screen, but it excels in portability due to its lighter weight and a battery that supports longer use away from power outlets. In comparison, the MSI GP66 Leopard also offers generous memory and storage with a powerful Intel CPU and a vivid IPS display, but it's more suited to stationary use with a heavier build and shorter battery life, though it provides an advantage for those needing intense processing power due to a more robust graphics card.

Although they have very similar scores, PerfectRec considers Lenovo Legion Slim 5 to be very good for engineering and design, while the MSI GP66 Leopard is good.
The Lenovo Legion Slim 5 stands out for engineering and design due to its newer AMD Ryzen CPU and RTX 4060 GPU, ensuring robust performance with demanding software, and its high-quality screen with a good balance of color accuracy and contrast is beneficial for detailed work. Meanwhile, the MSI GP66 Leopard, while still powerful with an Intel i7 CPU and RTX 3080 GPU, emphasizes gaming performance and will excel in raw graphics processing, but offers less battery capacity and portability than the Slim 5, making it a secondary option for users who prioritize mobility and battery life alongside computing capabilities.

"The Lenovo Legion Slim 5 Gen 8 acknowledges that a gaming laptop doesn’t have to be as thick as possible and can still ensure adequate cooling when the muscles need flexing. To this end, in the Slim 5 Gen 8, it finds a neat balance of refined, trimmed-down design that still lets its internals cruise (even above their max power ratings). Lenovo then added in some high-end build quality with an altogether excellent keyboard that’s useful for both work and play."

"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."
