Choosing between the ASUS ZenBook Pro 14 Duo and the Dell G15 5520 comes down to prioritizing features that are important to you. The ZenBook Pro, while more expensive, offers a higher resolution OLED touchscreen with compelling color accuracy, making it suitable for tasks requiring visual precision, like photo editing or design work. Its dual-screen features enhance multitasking but reduce battery life compared to typical laptops. On the other hand, the Dell G15 5520 has a gaming aesthetic, robust graphics capabilities thanks to its RTX 3060 GPU, and is geared towards gaming and high-performance tasks. Although less colorful, its display supports fast-paced games with a higher refresh rate. However, it's heavier and has a more standard display, which might be less appealing if portability and screen quality are your main concerns. Give Feedback

"The Zenbook Pro 14 Duo OLED is a well-tuned instrument for content creators, excelling at a range of general office tasks as well as tasks that require a little more grunt like encoding and 3D rendering. The big attraction is the laptop’s dual displays. They’re the best ones we’ve used in an Asus Zenbook Duo laptop to date with a spate of year-on-year improvements that make the visuals more striking and the cross-screen integration easier than ever before."

"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."
