The Dell Inspiron 15 3511 is more budget-friendly and offers a full-size screen with decent performance for everyday tasks, but if you need better battery life and a higher-resolution screen in a lighter package, the LG Ultra 16, though usually pricier, provides those benefits. The Dell may suit general office or schoolwork while the LG, with its long battery life and portable design, would be suitable for those who are frequently on the go. Neither is ideal for high-end gaming or demanding engineering software, but for casual games or light media editing, both should suffice, with LG potentially delivering slightly better graphics performance.

The LG Ultra 16 has a better screen than the Dell Inspiron 15 3511 for general use, and content creation.
For general use, the Dell Inspiron 15 3511 and LG Ultra 16 offer screens that are suitable for tasks like browsing and watching videos, but their average resolution and brightness levels might not stand out for vivid detail or outdoor visibility. In engineering and design, although these laptops have reasonable screen quality, professionals might find the color representation limited due to less coverage of professional color gamuts, impacting color-sensitive work. When it comes to gaming and 3D applications, the lower refresh rates on both laptops could lead to less fluid motion and a less immersive experience, despite their adequate resolution and panel types for casual use.

The LG Ultra 16 and Dell Inspiron 15 3511 are both only fair for gaming and AI.
The Dell Inspiron 15 3511 and the LG Ultra 16 are both deemed fair for gaming and 3D due to their integrated graphics units which offer moderate performance suitable for some gaming and 3D applications, but not the highest quality or fastest framerates that dedicated gaming GPUs would provide. Both laptops have 60Hz screens which are standard for most tasks, but aren't as smooth as higher refresh rates found in gaming-specific devices; however, their screens are of IPS type, which generally means better color reproduction and viewing angles, which is beneficial to screen quality, while CPU performance is also adequate for gaming.

The Dell Inspiron 15 3511 is equipped with a capable Intel i5 CPU, 32GB of RAM, and an integrated Intel Iris Xe GPU, making it a solid choice for engineering software and multitasking, along with a decent screen; however, its larger size and weight make it less portable. In contrast, the LG Ultra 16 offers an AMD Ryzen 7 CPU with Vega 8 graphics and 16GB of RAM, which can adeptly handle engineering tasks, also featuring a higher-resolution screen with better brightness and a lightweight design that enhances its portability, despite having less RAM and storage capacity.

Zachary Cuevas | November 2021
"The Dell Inspiron 15 3000 (3511) is a solid, if unremarkable, 15-inch budget laptop. It improves on many of the issues we had with the previous 3505 model, and with the inclusion of Windows 11, the 3511 is already a step above its competition. The lack of a USB-C port, the subpar speakers, and the dim display are drawbacks to factor in, but it's still one of the better 15-inch budget laptops on the market, especially when you consider it's under $400."

"Unlike the gram, the Ultra PC isn't designed to be as lightweight as possible. The 16-inch laptop is a whole 400 g (0.88 lb) heavier than its 16-inch gram counterpart partly because its chassis is not made of magnesium. Other than that, the Ultra PC seems like a copy of the gram – but with longer battery life, lower noise levels, and a clean, delicate look."
