Deciding between the Asus ZenBook Flip S13 and the Lenovo ThinkPad X13 requires weighing their strengths. The Asus offers a slim, lightweight design and a touchscreen that can be useful for creatives or presentations. However, its sleek form may come at a higher price and potentially lower durability compared to the ThinkPad. The Lenovo ThinkPad X13 is known for its robust build quality and business-oriented features, which might be more attractive if you prioritize a sturdy laptop with a keyboard that's comfortable for long typing sessions. Moreover, ThinkPads generally have good battery life and can handle a range of tasks from general use to business applications. If your work involves travel or you need a more versatile, convertible design, the Asus could be the better option, but for everyday productivity with a focus on typing comfort and build strength, the Lenovo may serve you better, often at a more budget-friendly price point.

The ASUS Zenbook Flip S13 has a better screen than the Lenovo ThinkPad X13 for general use, gaming and AI, and engineering and design, while the Lenovo ThinkPad X13 has a better screen for content creation, and software development.
The ASUS Zenbook Flip S13's superior screen quality for general use and engineering stems from its high resolution and brightness, alongside a wide color gamut that ensures vivid and accurate color reproduction, which is crucial for detailed design work. However, its poor screen quality for gaming and 3D applications is due to a lower refresh rate, which can lead to less smooth motion rendering. In contrast, the Lenovo ThinkPad X13, while still good for general use and engineering tasks with adequate resolution, brightness, and color range, falls short in gaming performance for the same reason of a lower refresh rate.

The Lenovo ThinkPad X13 and ASUS Zenbook Flip S13 are both only fair for gaming and AI.
The ASUS Zenbook Flip S13 and Lenovo ThinkPad X13 have GPUs that will handle games and 3D applications decently but won't deliver top-tier performance seen in dedicated gaming laptops. While both have capable CPUs and high-quality screens, their refresh rates are not as high as gaming-specific models, which can affect the fluidity of fast-paced visuals in gaming and some 3D tasks.

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."

"The Lenovo ThinkPad X13 G4 has very good input devices, a wide array of security features and ports as well as 5G in the tested configuration. It is more compact and lightweight compared with its predecessor, and it has improved speakers and a slightly better webcam. On the other hand, the fan is more annoying and the performance is barely improved. The battery is worse as well, but this is primarily attributable to the OLED screen - if this aspect is important, buyers should choose the IPS Low Power LCD."
