The ASUS ROG Strix Scar 17 is significantly more expensive than the Lenovo Flex 5 16, but offers superior gaming performance, a higher refresh rate screen, and better hardware for intensive engineering or 3D/machine learning tasks. However, it has a shorter battery life, is heavier, and may be less convenient for carrying around. Meanwhile, the Lenovo Flex 5 16 is more affordable and portable with a longer battery life, a sharper and brighter screen with touch capability and a higher resolution, making it more suitable for general use, but it lacks the high performance of the ASUS for gaming or professional applications.

"Asus ROG Strix Scar 17 laptop review: liquid metal 7 nm AMD Zen 3 is stunning. The raw performance increase is absolutely bonkers if you're upgrading from a laptop on Coffee Lake-H or older. The 45 W Ryzen 9 5900HX is neck-to-neck with the thicker, heavier, and hotter Schenker Ultra 17 running on a desktop-class Core i9-11900K despite their wide TDP differences. The performance-per-watt advantages can make Intel Rocket Lake feel like a last generation platform at times. As for the chassis itself, it's a huge light show with RGB LEDs on almost all sides of the system."

"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."
