The Lenovo Legion Slim 5 is a great choice for intensive engineering tasks, 3D rendering, and gaming due to its powerful GPU and CPU, but it is heavier and has shorter battery life, making it less portable. In contrast, the LG Ultra 13 offers significantly better portability with longer battery life and a much lighter design, suitable for general use and basic tasks. It is also more affordable, but not as well-suited for demanding applications due to its less powerful integrated graphics and processor. Consider the Lenovo if performance is a priority and the LG if you value portability and battery life for everyday tasks. Give Feedback

The Lenovo Legion Slim 5 is good for gaming and AI, while the LG Ultra 13 is only fair.

The Lenovo Legion Slim 5 is very good for engineering and design, while the LG Ultra 13 is only fair.
The Lenovo Legion Slim 5 has a stronger CPU and dedicated GPU, making it more suitable for demanding engineering and design tasks, along with better screen quality due to its contrast ratio and refresh rate, while the LG Ultra 13's CPU is less powerful without a dedicated GPU, and a lower contrast ratio and refresh rate, though it's lighter and offers longer battery life, making it more portable. However, if engineering and design performance are prioritized over portability and battery life, the Lenovo Legion Slim 5 is the better option.

Mark Knapp | August 2023
"The Lenovo Legion Slim 5 Gen 8 acknowledges that a gaming laptop doesn’t have to be as thick as possible and can still ensure adequate cooling when the muscles need flexing. To this end, in the Slim 5 Gen 8, it finds a neat balance of refined, trimmed-down design that still lets its internals cruise (even above their max power ratings). Lenovo then added in some high-end build quality with an altogether excellent keyboard that’s useful for both work and play."

"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."
