The ASUS ZenBook Pro Duo 15, being in the upper midrange price bracket, is more expensive than the Dell Inspiron 14 7435, which falls under the lower midrange. The ASUS comes with a more powerful Intel i9 processor and Nvidia RTX 3070 Ti graphics, making it better suited for intensive engineering tasks, 3D modeling, machine learning, and gaming, whereas the Dell’s AMD Ryzen 7 processor with integrated Vega 8 graphics is adequate for general use and can also handle some lightweight engineering work. The ASUS offers superior display quality with its OLED panel and is better for color-sensitive work, but it is heavier and has a shorter battery life compared to the Dell’s IPS screen, which also supports a touchscreen but with less color accuracy. If portability and battery life are priorities, the Dell is the lighter option and offers longer usage on a single charge. However, if top-notch performance and a high-quality display are a must-have and cost is less of a concern, the ASUS would be the laptop to go for. Give Feedback

The ASUS Zenbook Pro Duo 15 has a better screen than the Dell Inpsiron 14 7435 for general use, gaming and AI, engineering and design, software development, and content creation.
The ASUS ZenBook Pro Duo 15 has excellent screen resolution and brightness, along with high-quality panel technology, making it ideal for general use and tasks that require color accuracy such as engineering and design, due to its wide color gamuts.

"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."

"We see no shame in an economy laptop missing the four-star mark. Frankly, we considered giving the Inspiron 14 2-in-1 three-and-a-half stars for its low price, competitive performance, and long battery life. Unfortunately, working with a screen that can't deliver at least 300 nits of brightness is simply no fun to the point of detrimental. Still, if you're looking for a convertible laptop on a tight budget, it's worth keeping an eye on Dell's sales and discounts. That Lavender Blue model is fairly tempting."
