The ASUS ROG Strix G17 is a better choice if you need high performance for gaming, intensive engineering tasks, or 3D/machine learning applications, thanks to its powerful processor and advanced graphics card. However, it's heavier and less portable than the Lenovo Flex 5 16. On the other hand, if you're looking for a more affordable, lighter laptop with a touch screen and a longer battery life that can handle general use and still offers decent performance for less demanding engineering tasks, the Lenovo Flex 5 16 might be the better option for you.

The ASUS ROG Strix G17 has a better screen than the Lenovo Flex 5 16 for general use, gaming and AI, engineering and design, and content creation.
The ASUS ROG Strix G17 likely has a high resolution and bright display, which enhances user experience for general use and is crucial for precise engineering and design work, along with a wide color gamut beneficial for professional color accuracy. The Lenovo Flex 5 16 mirrors these qualities with a slightly lower level of brightness and color range but is still quite suitable for general and design tasks. However, both laptops fall short for gaming and 3D applications due to lower refresh rates, meaning they can't display quick-moving visuals as smoothly as models designed specifically with high refresh rate screens for gaming.

How the ASUS ROG Strix G17 and the Lenovo Flex 5 16 compare to other laptops
"The Asus ROG Strix G17 is an attractive but unbalanced gaming laptop. Its potent AMD Ryzen 9 processor excels in 1080p gaming, but playing at 1440p leaves the middling GeForce RTX 4060 GPU shouldering most of the burden. The display is exceptionally colorful, which is handy for content creators, but since this is a gaming laptop it would be better served with improved HDR capabilities. If battery life isn't a priority, the Strix G17 could serve as a designer by day and a gamer by night."
"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."
