The Lenovo Legion 7 is a more budget-friendly option with a midrange price and offers good performance for general use and gaming. It is relatively portable and has a decent battery life, which might suit you if you move around a lot. In contrast, the Razer Blade 18 is more expensive but comes with a more powerful processor and graphics card, which is better suited for intensive 3D tasks, machine learning, or engineering software. It also has a larger screen size and higher max refresh rate for a smoother visual experience but is heavier and has a shorter battery life, which could be less convenient for frequent travel.

The Razer Blade 18 is very good for gaming and AI, while the Lenovo Legion 7 is good.
The Lenovo Legion 7's Nvidia RTX 3070 and 165Hz screen refresh rate make it good for gaming and 3D applications, while the Razer Blade 18's superior Nvidia RTX 4070 GPU and higher 240Hz refresh rate elevate it to excellent for those same tasks, though the latter's top-tier components come with a higher price tag. Additionally, while both have high-quality CPUs and screen quality, the Razer Blade 18's more advanced CPU and slightly better screen attributes could provide a smoother and more vibrant experience, particularly evident in demanding gaming and 3D scenarios.

The Razer Blade 18 is excellent for engineering and design, while the Lenovo Legion 7 is very good.
The Lenovo Legion 7's AMD Ryzen 7 CPU and Nvidia RTX 3070 GPU provide a strong foundation for engineering and design tasks, with a large, high-resolution screen enhancing visuals, but the Razer Blade 18 surpasses this with a more powerful Intel i9 CPU and Nvidia RTX 4070 GPU paired with a larger, brighter display which is excellent for detail-oriented work. While the Razer Blade 18 has a significant edge in raw performance and screen quality which is crucial for engineering and design work, it is also less portable and louder under load, which may impact its use in quiet environments or when mobility is a necessity.

"The Lenovo Legion 7 is a fast 16-inch gamer with 165 Hz display. The new Lenovo Legion 7 is a very good gaming notebook that, despite its comparatively compact compact 16-inch case, does not have to do without the most powerful components. Thanks to good cooling, no compromises are made in terms of performance. Both the Core i9-12900HX and the GeForce RTX 3080 Ti perform at a very high level."

"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."
