The ASUS ZenBook Pro Duo 15 offers a strong performance for engineering and general use thanks to its powerful processor and high-quality OLED screen, ideal for tasks that benefit from good color representation, like video editing. It's less expensive and has a slightly better battery life, but it's heavier and less portable than the Razer Blade 18. On the other hand, the Razer Blade 18 is geared more towards gaming and high-end performance, featuring a faster refresh rate display and a more powerful graphics card, which makes it better for intensive gaming and 3D work. However, it's more expensive and has a shorter battery life, and while it has better portability than the ASUS, it's still on the heavier side. Choose the ASUS if you value screen quality and cost-effectiveness for professional creative work, or the Razer if gaming performance and high refresh rates are your priority despite the higher cost and lower battery life.

"Benchmarks aside, the Asus ZenBook Pro Duo is hard to compare with other PCs. Its closest competition may be a multi-monitor desktop, or a laptop with an attached travel monitor. The Pro Duo is more portable and versatile than either of those options, especially with the software tools Asus has thrown on top. For a certain niche of artists, media creators, and gamers, all that might add up to something special, even if it’s unattainable for the rest of us."

"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."
