If you prioritize high-end performance for demanding engineering tasks, video editing, or gaming, and you don't mind a heavier laptop with a shorter battery life, the ASUS ZenBook Pro Duo 15 with its advanced processor and powerful dedicated graphics may suit you well. However, consider the Dell Inspiron 14 Plus if you prefer something more affordable, portable, and with longer battery life for general use or less intensive 3D tasks, though it has a less powerful integrated graphics and a smaller screen. Both have high-quality displays, but the ASUS offers a superior color experience, which is beneficial for creative work. Give Feedback

The ASUS ZenBook Pro Duo 15 is very good for general use, while the Dell Inspiron 14 Plus is good.
The ASUS ZenBook Pro Duo 15 stands out for general use with a higher-end CPU and double the RAM of the Dell Inspiron 14 Plus, as well as a superior OLED screen that provides better color coverage and brightness, enhancing visual experience greatly. However, the Dell Inspiron is lighter and more compact, which alongside a slightly better battery life, makes it more portable for everyday use despite having a less powerful integrated GPU and lower screen resolution compared to the ASUS.

The ASUS ZenBook Pro Duo 15 is excellent for engineering and design, while the Dell Inspiron 14 Plus is good.
The ASUS ZenBook Pro Duo 15 excels in engineering and design due to its powerful Intel i9 CPU, copious 32GB of RAM, high-end Nvidia RTX GPU, and superior OLED screen quality that offers excellent contrast and color coverage, making it very good for tasks requiring visual precision and computational horsepower, albeit at the expense of being heavier and less portable. In contrast, the Dell Inspiron 14 Plus, while still suitable for engineering and design with a capable Intel i7 CPU, 16GB of RAM, and a decent IPS screen, is more portable and has a better balance of keyboard and speaker quality, but it lacks the dedicated GPU and the dazzling screen quality of its ASUS counterpart, resulting in just "good" performance for these specialized tasks.

The ASUS Zenbook Pro Duo 15 has a better screen than the Dell Inspiron 14 Plus for general use, gaming and AI, engineering and design, software development, and content creation.
The ASUS ZenBook Pro Duo 15 boasts a high-resolution display and exceptional color accuracy, making it ideal for engineering and design tasks that require precise color representation, but its standard refresh rate is a drawback for gaming where smoother motion is key. Meanwhile, the Dell Inspiron 14 Plus offers a balance of good resolution and brightness for daily activities and sufficient color reproduction for most design work, yet it also falls short for gaming due to a less optimal refresh rate. For general use, both laptops provide clear and vibrant visuals, but gamers and 3D designers should consider other options tailored for their high refresh rate requirements.

"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."

"The Dell Inspiron 14 Plus is for power users on a budget. If you're looking to maximize CPU and GPU performance on your next 14-inch laptop, then consider the pricier Razer Blade 14 or Asus Zephyrus G14. If you're looking for a thin-and-light 14-inch Ultrabook, then the Asus Zenbook 14 or LG Gram 14 may be better options. For the best of both worlds, however, the Dell Inspiron 14 Plus 7420 rides a fine line between extreme performance and portability while keeping prices at reasonable levels. Frequent travelers who rely on performance beyond what the Core U-series and integrated graphics series can offer will find the Dell to be a solid solution."
