The ASUS ROG Strix Scar 15 is a high-performance laptop with a strong graphics card, making it suitable for intensive gaming, 3D rendering, and engineering software. It is less portable and has a shorter battery life. If you prefer excellent performance for demanding tasks and can manage with less mobility, it's a solid choice. On the other hand, the Lenovo Flex 5 16 is more affordable, lighter, and offers longer battery life, plus a touchscreen with higher resolution. It's better for general use, lightweight engineering tasks, and if you're on the go. However, it's not suitable for intensive gaming or heavy 3D work. Give Feedback

The ASUS ROG Strix Scar 15 is very good for engineering and design, while the Lenovo Flex 5 16 is good.
The ASUS ROG Strix Scar 15 stands out for engineering and design due to its superior Intel i9 processor and dedicated Nvidia RTX graphics, making it well-suited for demanding tasks, but it's heavier and has a shorter battery life. Conversely, the Lenovo Flex 5 16 offers a higher resolution screen and better portability with a longer battery life and lighter build, but its integrated Intel graphics and less powerful i7 processor make it less ideal for intensive engineering software and design work.

How the ASUS ROG Strix Scar 15 and the Lenovo Flex 5 16 compare to other laptops
"Asus continues to refine the ROG Strix Scar lineup with new upgrades. The Asus ROG Strix Scar 15 offers almost everything you would expect from a gaming laptop at this price. The build quality is great, connectivity options are decent, and there is enough scope for internal upgrades as well. Asus reverts to membrane switches for the keyboard — though not as "clickety" as the opto-mechanical ones we saw with last year's model, they still make for a decent typing and gaming experience. The lack of biometrics in any form is a downer."
"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."
