The MSI Stealth GS77 is very good for engineering and design, while the Lenovo Flex 5 16 is good.
The Lenovo Flex 5 16, with its lower-tier CPU and integrated graphics, is suitable for less demanding engineering and design tasks, and its 2-in-1 convertible feature may appeal to those prioritizing versatility and moderate power. In contrast, the MSI Stealth GS77 offers a high-end CPU and dedicated graphics card for more intensive engineering and design work, though its larger size and weight make it less portable.

The MSI Stealth GS77 has a better screen than the Lenovo Flex 5 16 for general use, gaming and AI, engineering and design, content creation, and software development.
For general use, the Lenovo Flex 5 16 and MSI Stealth GS77 both offer screens with resolutions and brightness levels that facilitate crisp text and vibrant display, making them suitable for everyday tasks. In the realm of engineering and design, the color accuracy, including DCI-P3 and Adobe RGB coverage, is crucial for precise work; the MSI Stealth GS77 excels in this area, offering a wider range of colors than the Lenovo Flex 5 16. However, for gaming and 3D applications where high refresh rates are key to smooth visuals, both laptops fall short as their screens are not designed with high refresh rates in mind, leading to less fluid motion during fast-paced scenes.

"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 GS77 is better than the GS76... mostly. The GS77 is a few steps forward and a few steps back from the GS76. Improvements are numerous including the stronger and more rigid skeleton, higher resolution webcam, larger clickpad, easier serviceability, relatively similar battery runtimes, newer display options, and higher performance at about the same TDP and TGP levels as before. CPU performance is better than expected even when compared to other laptops with Core i7 or Core i9 processors. The newer model feels more substantial than the outgoing one for higher quality impressions as well."
