The LG Ultra 16 is typically much less expensive and offers significantly longer battery life, adding to its portability; it's also lighter. However, if performance, particularly for 3D rendering, machine learning, and gaming, is a priority, the Razer Blade 18, with its more powerful processor and dedicated high-end graphics, is better suited, though it comes at a higher cost and reduced battery life. Both are similar in build quality, with the Razer Blade offering superior keyboard and speaker quality, making it more suited for intensive gaming and professional creative tasks, while the LG prioritizes quiet operation and general use.

The Razer Blade 18 has a better screen than the LG Ultra 16 for general use, gaming and AI, engineering and design, content creation, and software development.
When focusing on general use, the LG Ultra 16 delivers satisfactory visuals with enough resolution and brightness for typical tasks, but the Razer Blade 18 offers sharper and brighter images making it ideal for both media consumption and productivity. The Razer Blade 18 stands out for engineering and design work due to its superior color accuracy and wider color gamuts, ensuring that professionals who require precise color rendition for their projects are well-served. However, for gaming and 3D applications, both laptops fall short as they lack high refresh rates, which are crucial for smooth motion and immersive gameplay, despite having decent resolutions and panel types that could handle less demanding visual tasks.

"Unlike the gram, the Ultra PC isn't designed to be as lightweight as possible. The 16-inch laptop is a whole 400 g (0.88 lb) heavier than its 16-inch gram counterpart partly because its chassis is not made of magnesium. Other than that, the Ultra PC seems like a copy of the gram – but with longer battery life, lower noise levels, and a clean, delicate look."

Matthew Buzzi | March 2023
"Razer made a powerful laptop in the Blade 18, showing off a beautiful and fast display and the same high-quality build we’ve come to expect from this product line. It’s also quite expensive, which is hardly a surprise, but bears repeating even in this price range. It’s pricier than the Scar 18 despite an inferior GPU and half the storage, so you really have to want the Blade 18’s design to justify the cost."
