If you need a more powerful laptop for gaming or intensive engineering tasks with a high refresh rate display, the ASUS ROG Strix G15 Advantage Edition is well-suited, but be prepared for a heavier and larger device that's less portable and has a shorter battery life. In contrast, the Lenovo Flex 5 14 offers a lighter, more compact form factor with a longer battery life and a touchscreen, making it better for portability and general use, but it's less equipped for demanding tasks or gaming due to its integrated graphics. Choose the ASUS for performance or the Lenovo for on-the-go convenience and efficiency. Give Feedback

The ASUS ROG Strix G15 Advantage Edition has a better screen than the Lenovo Flex 5 14 for general use, gaming and AI, and engineering and design.
In selecting a laptop for general use, the ASUS's high resolution and bright display may enhance everyday browsing and video streaming experiences, while the Lenovo's display, though fair for daily tasks, may not be as vibrant or sharp. For engineering and design tasks which require accurate color representation, the ASUS likely offers wider color coverage, making it suitable for professionals who need precise color fidelity; however, the Lenovo still provides fair color reproduction for casual designing. When it comes to gaming and 3D applications, the faster refresh rate of the ASUS would be less impressive due to its poorer screen quality for this use case, while the Lenovo, despite its fair overall quality, will also fall short for gamers and 3D enthusiasts seeking fluid motion and detailed visuals.

How the ASUS ROG Strix G15 Advantage Edition and the Lenovo Flex 5 14 compare to other laptops
"The Asus ROG Strix G15, as the first in a line of "AMD Advantage"-branded notebooks, is a statement that yes, you can get a premium AMD gaming notebook. Maybe you can't have it all, but you can get pretty close. The ROG Strix G15's combination of the AMD Ryzen 5900HX and Radeon RX 6800M, as well as other technologies that take advantage of them, make a potent, thin gaming machine. Powerful Dolby Atmos speakers and long battery life when you aren't gaming are nice bonuses."
"The highlight of the latest IdeaPad Flex 5 14 is clearly its AMD CPU. The octa-core Ryzen 7 5700U is insanely fast even when compared to the best Tiger Lake Ultrabooks in the market or even Core H CPUs in many gaming laptops. It's a lot of raw processing power for what is supposed to be a budget 14-inch convertible. If your daily workloads can benefit from extra multi-thread CPU performance, then look no further than the inexpensive AMD-powered Lenovo IdeaPad Flex 5 14. For regular on-the-road browsing or video streaming, however, a slimmer and lighter 10th gen Core Yoga, Spectre, or XPS would be a more balanced option."
