If you prioritize gaming with good graphic settings, the Lenovo Legion 5 with its RTX 3060 graphics may provide better performance compared to the ASUS ROG Strix G15 with an RTX 3050 Ti. However, if you value battery life and a slightly more portable design, the ASUS has a higher battery capacity and weighs less than the Lenovo. Both have decent processing power for general use and engineering tasks but the Lenovo's larger screen might be more suitable for multitasking and immersive experiences, albeit at the cost of reduced portability. Both have similar capacities for upgrades in RAM and storage, so future expandability is comparable. If you often work in well-lit areas, the Lenovo's brighter screen might be advantageous. Both laptops have non-touch IPS displays with the same resolution and refresh rate, offering quality visuals, but neither is ideal for color-sensitive work due to moderate color space coverage. It comes down to whether you prefer gaming capabilities and screen size over battery life and easier handling. Give Feedback

The ASUS ROG Strix G15 and Lenovo Legion 5 17" are both good for general use.
The ASUS ROG Strix G15 is suited for general use due to its capable AMD Ryzen 9 processor and 16GB of RAM that can handle various tasks comfortably, along with a quality IPS screen; however, its portability and battery life are limited, which may not be ideal for on-the-go usage. Conversely, the Lenovo Legion 5 17" also matches in general performance capabilities with an Intel i7 processor and equivalent RAM, offers better screen brightness and a larger screen size, but it's less portable due to its larger form factor and heavier weight, with battery life also on the shorter side for extended mobility.

"The ASUS ROG Strix G15 is a successful high-performance 15-inch laptop. The Asus ROG Strix impresses with an elaborate design and fast hardware. The latter can unleash its potential well in the large 15-inch case and achieve a decent performance boost compared to the previous generation. Especially the stunning 300 Hz display as well as the RTX 3070 and its generous TDP give gamers their money's worth. Asus didn't neglect seemingly small details, either, such as the keyboard and the maintenance options. The ROG Strix G15 offers a lot of pure performance and excellent workmanship in a 15-inch format, but connectivity leaves something to be desired."

"The Lenovo Legion 5 17 is a current-gen 17-inch gaming laptop and equipped with the latest AMD CPU and a powerful GPU, that manages to reach its full potential. The AMD Ryzen 5 5600H is a very good choice for this laptop and able to maintain its performance level for long periods of time. Our test model only falls behind consistently in a direct comparison with its competitors that are often equipped with eight cores and 16 threads. Despite this, the Legion 5 17 leaves an excellent impression and is almost able to keep up with an Nvidia GeForce RTX 3070 mobile GPU in synthetic benchmarks."
