The ASUS ROG Flow X16 offers a more versatile experience with its touchscreen and higher resolution display that is also brighter and with better color coverage, which is beneficial for creative professionals or those who enjoy vibrant displays. It has a larger battery which could translate to longer usage times, but actual battery life can vary depending on usage. The Flow X16 is newer and slightly lighter, making it more portable, but the difference in weight with the Strix G15 is minimal. Both have the same amount of storage and RAM, but the Flow X16 has a more powerful GPU and a newer CPU, which could offer better performance for intensive tasks like 3D rendering or engineering software. In contrast, the ASUS ROG Strix G15 is tailored more towards gaming with its dedicated Ethernet port, and while it has a less powerful GPU and an older CPU, it still supports hardware ray tracing and DLSS which are features gamers appreciate. The Strix G15 has an edge in gaming aesthetics and is a viable option if you prioritize a traditional gaming laptop look and connectivity for competitive gaming. Both laptops are similarly priced, so the choice depends on whether you value a versatile touch display and slightly better performance (Flow X16) or a gaming-oriented design with sufficient performance for less demanding tasks (Strix G15).

"Above all else, the Asus ROG Flow X16 is one thing - versatile! It is a thin, mobile work device, it's a 2-in-1, tablet, a powerful workstation and even a gaming PC. But something even more surprising: It does all of these things really well without making any big blunders. It's anything but a lazy compromise. Because, despite its compact dimensions and 2-in-1 functionality, the hardware isn't throttled and boasts, at least in turbo mode, above-average performance."

"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."
