The ASUS Zenbook Pro 15 is more expensive but offers better performance with high-end components, making it suitable for intensive engineering tasks, 3D rendering, and machine learning. However, it's heavier which impacts portability. On the other hand, the LG Ultra 13 is more affordable and lighter, making it highly portable, but it has less powerful hardware which makes it less suited for demanding tasks. Both have good quality displays but the ASUS has an OLED screen, which is superior for color reproduction. Consider the ASUS if performance is a priority and the LG if you need something more portable and affordable. Give Feedback

The ASUS Zenbook Pro 15 is good for engineering and design, while the LG Ultra 13 is only fair.
The ASUS Zenbook Pro 15 is better for engineering and design due to its more powerful CPU and dedicated graphics card, which are crucial for performance-intensive applications, and its OLED display offers superior color accuracy and contrast for design work. Whereas the LG Ultra 13, while still offering adequate RAM for multitasking, comes with a less capable integrated GPU and a smaller IPS screen, which might not deliver the same level of detail and color fidelity but provides greater portability due to its lighter weight and smaller size.

The ASUS Zenbook Pro 15 has a better screen than the LG Ultra 13 for general use, gaming and AI, engineering and design, software development, and content creation.
The ASUS Zenbook Pro 15 offers vibrant color accuracy and high resolution, which benefits designers and engineers who need precise color representation for their work, making it very good for those use cases. When it comes to general use, the ASUS excels with its high resolution and brightness, ensuring that everyday tasks like browsing and video streaming are crisp and enjoyable. However, for gaming and 3D applications, its lower refresh rate makes fast-moving images less smooth compared to displays optimized for those activities, which is why it's considered poor for those specific needs.

"The ASUS Zenbook Pro 15 offers a strong CPU, chassis, and display. One of the most popular 15.6-inch prosumer or multimedia laptops out there is the Dell XPS 15. Thus, comparisons between it and the Asus Zenbook Pro 15 are inevitable. Asus has a couple of tricks up its sleeve that XPS users are still missing out on including 1080p OLED and an AMD Ryzen CPU which help separate the Zenbook Pro 15 from the XPS 15. It also integrates a numpad and a few more port options albeit at the cost of a larger chassis size."

"The 13.3-inch LG Gram is a fine fit if you need to travel as light as possible for as long as possible without spending a fortune to do it. It might not be particularly sturdy or have an eye-catching design and its webcam is less than ideal, but with its sharp touch display, comfortable backlit keyboard, responsive touchpad and a fingerprint reader for extra security, the Gram makes a respectible everyday laptop for business or school work."
