The ASUS Zenbook Flip S13 offers good performance and versatility as a convertible laptop that can switch between tablet and laptop modes, with a reasonable price for what it delivers. It is lightweight, making it suitable for on-the-go use, with decent battery life. On the other hand, the Razer Blade 18 offers top-tier performance, especially for gaming or demanding tasks like 3D and machine learning, but comes at a higher cost and is heavier, which affects its portability. The Razer Blade 18 is newer with more powerful components and a larger display but will have shorter battery life compared to the ASUS due to its high-performance hardware. Choose the ASUS for portability and value, or the Razer if high performance and a large screen are your top priorities. Give Feedback

Charles Jefferies | January 2023
"The Asus Zenbook S 13 Flip is an ultra-sleek 2-in-1 convertible. A gorgeous OLED screen and lightweight magnesium chassis make this convertible a traveller’s dream. Its SSD isn’t fast, but it won’t hold you back in everyday use. Its battery life also isn’t class leading, but it’s hardly off the pace. Overall, the Zenbook S 13 Flip OLED holds its head high in the premium convertible category and is a smaller alternative to the Spectre x360 13.5 and the Yoga 9i Gen 7."

"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."
