If you prioritize a lower price and greater portability, the LG Ultra 13, being lighter and more affordable, would be a good option, especially for general use such as browsing and office tasks. However, if you require higher performance for tasks like 3D modeling, machine learning, or gaming, the Razer Blade 15 would be preferable, with its more powerful CPU and GPU. It also has better build quality and higher screen resolution, but it's heavier and more expensive. The Razer's battery life is not as long as the LG's, which may be a consideration if you're often on the move. Give Feedback

The Razer Blade 15 is very good for engineering and design, while the LG Ultra 13 is only fair.
The LG Ultra 13's more modest AMD Ryzen CPU and integrated Vega 7 graphics are adequate for engineering and design but are overshadowed by the Razer Blade 15's higher-end Intel i7 CPU and discrete Nvidia RTX 3070 Ti GPU, which excel in those demanding tasks. Despite being lighter and more portable, the LG Ultra 13 can't match the screen quality and overall performance of the Razer Blade 15, which prioritizes power over portability.

The Razer Blade 15 has a better screen than the LG Ultra 13 for general use, gaming and AI, engineering and design, content creation, and software development.
The LG Ultra 13 offers suitable resolution and brightness for everyday tasks, but its lower refresh rates and less vibrant color spectrum may disappoint avid gamers or those engaging in high-frame-rate 3D applications. On the other hand, the Razer Blade 15's higher resolution and superior color accuracy meet the demanding needs of engineering and design professionals requiring precise color representation. However, despite its advanced specifications, the Razer Blade 15's screen may fail to satisfy gaming enthusiasts due to a refresh rate that is not as high as specialized gaming laptops.

Joshua Goldman | April 2017
"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."

Allen Ngo | March 2022
"The 2022 Blade 15 offers roughly 15 to 25 percent faster graphics performance and 20 percent faster CPU performance over last year's Core i7-11800H and RTX 3080 model. Thankfully, the system doesn't need to run noticeably louder or warmer to achieve faster results, but both power consumption and battery life take a hit. The higher consumption in particular appears to be a trend amongst many 12th gen Core laptops including the Schenker Uniwill Technology GM7AG8P or MSI Vector GP66 when compared to their previous generation counterparts. We're also glad to not see below-average CPU performance which was the case for the 10th gen Core i7-10875H model."
