If your priority is higher portability and battery life at a lower cost while still getting solid general use performance, consider the ASUS Zenbook Duo. It also has a unique dual-screen design which can be beneficial for multitasking. However, if you need higher performance for tasks like 3D rendering, machine learning, or gaming, the Razer Blade 15 with its more powerful graphics card and processor is a better fit, but it's heavier, has shorter battery life, and is more expensive. Both laptops have similar amounts of storage and memory, but the Razer provides additional slots if you plan to upgrade. Additionally, the Razer Blade's screen is preferable for color-intensive tasks due to higher color accuracy and contrast, and it has a higher refresh rate beneficial for fast-paced gaming.

Allen Ngo | May 2020
"The Asus ZenBook Duo's second screen is like the Apple Touch Bar, but better. Most would agree that having two screens instead of one can really boost productivity and the ZenBook Duo is no different in this regard. It's tough going back to just one screen after becoming accustomed to spacious dual-screen setups. For a laptop form factor, however, users will have to accept some compromises. Firstly, weight is the most obvious drawback as the system is several hundred grams heavier than a regular ZenBook 14. Additionally, colors on the second screen will not be as vivid as the main display."

"The 2022 Blade 15 offers roughly 15 to 25 percent faster graphics performance and 20 percent faster CPU performance over last year's Core i7-11800H and RTX 3080 model. Thankfully, the system doesn't need to run noticeably louder or warmer to achieve faster results, but both power consumption and battery life take a hit. The higher consumption in particular appears to be a trend amongst many 12th gen Core laptops including the Schenker Uniwill Technology GM7AG8P or MSI Vector GP66 when compared to their previous generation counterparts. We're also glad to not see below-average CPU performance which was the case for the 10th gen Core i7-10875H model."
