The ASUS Zenbook Duo 14 is lighter and more portable than the Dell G15 5520, making it better for on-the-go use. It also comes with a second display, which can be useful for multitasking or creative tasks, and has a better battery capacity. Conversely, the Dell G15 has a more powerful CPU and GPU combo, providing better overall performance for gaming, 3D modeling, or engineering software. It has a higher screen refresh rate, which is ideal for fast-paced gaming but lacks a touchscreen. Choose the ASUS for portability and multitasking, or the Dell for high-performance tasks and gaming.

NotebookCheck

Allen Ngo | May 2020
"The Asus ZenBook Duo's second screen is like the Apple Touch Bar, but better. Most would agree that having two screens instead of one can really boost productivity and the ZenBook Duo is no different in this regard. It's tough going back to just one screen after becoming accustomed to spacious dual-screen setups. For a laptop form factor, however, users will have to accept some compromises. Firstly, weight is the most obvious drawback as the system is several hundred grams heavier than a regular ZenBook 14. Additionally, colors on the second screen will not be as vivid as the main display."

Olivier Martin, Ryan Lim, and John Peroramas | April 2023
"The Dell G15 (2022) is a 15.6-inch budget gaming laptop, and is great for gaming. You can configure the laptop with powerful Intel 12th Gen. CPUs and various NVIDIA dedicated GPUs, all of which deliver a smooth gaming experience at 1080p. There's also a QHD 240Hz display option if you want better visuals, though you'll have to pair it with the top-end NVIDIA GeForce RTX 3070 Ti to get good frame rates. It doesn't get overly hot or loud under load, and there's no noticeable throttling on the CPU or GPU. Unfortunately, the 120Hz panel has a slow response time, causing noticeable ghosting, and it doesn't support variable refresh rate."
