The Lenovo Legion Slim 5 is less expensive and lighter, making it good for general use and day-to-day portability. However, if you require a laptop for more demanding tasks such as intensive gaming, 3D rendering, or engineering software, the Razer Blade 18, while more expensive and slightly heavier, offers superior performance and a larger and higher-resolution display, which could justify the additional cost for those who need these capabilities.

The Razer Blade 18 is excellent for engineering and design, while the Lenovo Legion Slim 5 is very good.
The Lenovo Legion Slim 5, with its AMD Ryzen CPU and Nvidia RTX 4060 GPU, offers solid performance for engineering and design tasks but the Razer Blade 18 outshines it with a more powerful Intel i9 CPU and Nvidia RTX 4070 GPU, paired with higher RAM and better screen resolution for more demanding work. However, the Legion Slim 5 is lighter and potentially more convenient for on-the-go use, whereas the Blade 18, despite being less portable due to its larger screen and heavier weight, comes with superior keyboard and speaker quality for a more comfortable user experience, though it may produce more operating noise.

"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."

"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."
