The ASUS Zenbook Duo is more wallet-friendly and offers good general use, a dual-screen setup for multitasking, and very good portability with longer battery life, making it suited for everyday tasks and mobility. The Razer Blade 18, on the other hand, is pricier but provides top-tier performance for gaming, 3D rendering, and engineering software, accompanied by a larger and higher-refresh-rate screen, though it's less portable due to greater weight and shorter battery life. If budget is tight and portability is key, go for ASUS; for maximum performance in demanding tasks and gaming, Razer is the better option. Give Feedback

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."

"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."
