The Lenovo Flex 5 16 offers a versatile 2-in-1 design with a touchscreen and is generally more affordable. It's suitable for general use and has a decent battery life, making it good for those who prioritize portability and moderate use without needing high-performance features. On the other hand, the MSI Stealth GS66, while more expensive, boasts higher-end specs including a powerful graphics card, making it more suitable for gaming, 3D rendering, and engineering tasks. It also has a high refresh rate display for smoother visuals but comes with shorter battery life, which lessens its portability. Thus, if your work requires intensive graphics and processing power and you're less concerned about price and battery life, the MSI would be a better fit, whereas the Lenovo is a balanced choice for everyday productivity and media consumption at a more budget-friendly price point.

The MSI Stealth GS66 is good for gaming and AI, while the Lenovo Flex 5 16 is only fair.
The MSI Stealth GS66 offers superior gaming and 3D performance over the Lenovo Flex 5 16 primarily due to its high-end Nvidia RTX 3070 Ti graphics card and a high 360Hz screen refresh rate, which are integral for smooth and detailed visual experiences in intensive games and 3D applications. In contrast, the Lenovo Flex 5 16 is equipped with a less powerful Intel Iris Xe graphics and a standard 60Hz refresh rate, which may be adequate for casual gaming and light 3D work but falls short for enthusiasts seeking the highest performance.

How the Lenovo Flex 5 16 and the MSI Stealth GS66 compare to other laptops
"The Lenovo IdeaPad Flex 5 is a solidly equipped, 2-in-1 in the lower price segment. Performance is definitely sufficient for everyday tasks and in tests the battery proved itself to be very economical. That aside, there is a lot of standard fare on show and a search for real highlights ends in vain. The low color coverage and reflective display can be avoided by going for an optional 2.5K display but this also presumably results in poorer battery life. The cooling uses only one fan and leads to a raised temperature on one side of the device under load. Additionally, there is very loud fan noise, also under load or when gaming. On top of that, we also occasionally noticed electronic noises."
"The MSI Stealth GS66 is powerful enough for QHD. The Core i7-12700H and the GeForce RTX 3070 Ti found in the 12UGS model that we tested run all modern games smoothly in the native QHD resolution. The 15-inch display is very fast with its 240 Hz refresh rate, and it also offers a great color space (almost 100% DCI-P3) on top of that, which should please gamers as well as content creators, although we would have still wished for a higher brightness. Case, input devices, and connectivity (Thunderbolt 4) are at a good level. However, among other things, the GS66 loses points due to the high temperature development in 3D mode and its poor webcam."
