If you prioritize a less expensive option that still offers solid performance but with the flexibility of a detachable keyboard for tablet use, the ASUS ROG Flow Z13 is a good choice, also being lighter and more portable. However, if you need more power for demanding tasks like gaming or content creation and don't mind the additional cost and larger size, the Razer Blade 18 with its larger screen and stronger graphics capability will be more suitable, albeit with a significant increase in weight and reduced portability. Both have high-resolution displays and are recently updated, ensuring current technology and performance. Give Feedback

The Razer Blade 18 is excellent for engineering and design, while the ASUS ROG Flow Z13 is very good.
The ASUS ROG Flow Z13 is robust for engineering and design due to its high-end CPU, capable GPU, and quality screen but is more portable with a detachable keyboard than the heavier, more expansive Razer Blade 18, which offers stronger performance with superior CPU, double the RAM, and a more powerful GPU, along with a larger, brighter screen that can boost productivity in design tasks. While both have high-quality screens and sufficient ports for peripherals, the Razer Blade 18 has the edge in raw power and screen size, which might justify its lower portability and higher operating noise for users prioritizing top-tier engineering and design work over mobility.

How the ASUS ROG Flow Z13 and the Razer Blade 18 compare to other laptops
"The Asus ROG Flow Z13 is a gaming tablet with powerful Alder Lake i9 CPU. The ROG Flow Z13 impresses with its good cooling. After our review, the impression is predominantly positive. Besides a very fast Alder Lake CPU and stable gaming performance, especially the cooling system is surprisingly effective and quiet. You can use the integrated speakers without any issues while gaming. The 1200p display in the 16:10 format also impresses with good color reproduction and high brightness. Since the battery runtimes aren't particularly long as it is, we wouldn't recommend the optional 4K panel."
"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."
