The Lenovo Slim Pro 9i is much more expensive and offers better performance for intensive tasks like 3D rendering, machine learning, and engineering, with a high-quality display and graphics card. However, it's less portable and has shorter battery life. The LG Ultra 13 is much less expensive and extremely portable, with longer battery life, but with less storage, lower performance, and a simpler graphics setup, making it suitable for general use but not for demanding applications. Both have backlit keyboards and are suitable for gaming, but the Lenovo is better equipped for intensive gaming. Give Feedback

The Lenovo Slim Pro 9i is very good for general use, while the LG Ultra 13 is good.
The Lenovo Slim Pro 9i excels in general use due to its more powerful Intel CPU, ample RAM, and superior Mini LED display which enhances screen quality; however, this comes with less portability and shorter battery life compared to the LG Ultra 13. The LG Ultra 13, while more portable with a longer battery life and good for general use, has a less powerful AMD CPU and lower RAM, contributing to slightly reduced performance.

"The Lenovo Slim Pro 9i is an impressive laptop with a brilliant Mini-LED display, a powerful 100-watt version of Nvidia RTX 4050 graphics, and excellent connectivity. Having run the Cinebench benchmark again, we were impressed with the CPU performance. That makes the Slim Pro 9i is an easy recommendation, especially for those who care about GPU and CPU performance. It’s also a fantastic choice if you frequently view HDR movies and games on your laptop."

"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."
