The Razer Blade 18 is very good for general use, while the ASUS ROG Strix G15 is good.
The Razer Blade 18 outperforms the ASUS ROG Strix G15 for general use, not only due to its sharper and brighter display but its more powerful processor and double the RAM, catering to more demanding multitasking and applications; however, these perks come at the expense of lower battery life and reduced portability given its larger screen size and heavier build. The ASUS, while less powerful, offers a better balance between performance and portability, with a smaller screen size conducive to on-the-go use and longer battery lifespan between charges.

The Razer Blade 18 has a better screen than the ASUS ROG Strix G15 for general use, gaming and AI, engineering and design, content creation, and software development.
The ASUS ROG Strix G15's screen offers adequate resolution and brightness for typical tasks and solid color gamut coverage which benefits engineering and design work, but its lower refresh rate isn't ideal for the smoother visuals critical in gaming and 3D applications. Conversely, the Razer Blade 18 provides excellent resolution and brightness that enhance everyday use, alongside comprehensive color gamut support that professional design software requires, yet it also falls short on refresh rate, impacting gaming and 3D modeling experience. Overall, both laptops cater well to general productivity and creative workflows but might disappoint gamers and 3D designers looking for fluid motion and swift on-screen responses.

"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."

"Razer made a powerful laptop in the Blade 18, showing off a beautiful and fast display and the same high-quality build we’ve come to expect from this product line. It’s also quite expensive, which is hardly a surprise, but bears repeating even in this price range. It’s pricier than the Scar 18 despite an inferior GPU and half the storage, so you really have to want the Blade 18’s design to justify the cost."
