The Dell G15 5520 and Dell Inspiron 15 3511 are both good for general use.
The Dell G15 5520 is equipped with a high-end CPU, substantial RAM, and a quality screen, making it suitable for demanding tasks, but due to its weight and gaming laptop appearance, it isn't the most portable and has moderate battery life. Conversely, the Dell Inspiron 15 3511 features a mid-range CPU and more RAM for smoother multitasking, and despite having less powerful integrated graphics, it's lighter and marginally better in battery life, offering a balance for everyday use without the gaming flair.

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."

"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."
