When choosing between the Dell Inspiron 15 3511 and the HP Pavilion 15, consider that the Dell has a stronger processor, which makes it better for more demanding tasks, but it usually comes at a higher price. The Dell also has a higher quality display, which is better for viewing angles and color accuracy, and a backlit keyboard, making it usable in low-light conditions. On the other hand, the HP has a larger battery, potentially offering longer use between charges, and it's slightly lighter, which could be more convenient for mobility. Both laptops offer similar storage and have Windows 11 Home. If you prioritize performance and display quality for tasks like photo editing or multitasking and don't mind a higher price, the Dell might be the way to go. However, if you're looking for a laptop for basic tasks with better battery life and portability at a more affordable price, the HP could be a satisfactory choice. Give Feedback

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."

"The HP Pavilion 15 carries a fair amount of power and a sharp display in its handsome slimline shell. It's not perfect, but it's a hard worker. This is wonderfully designed and totes a heck of a lot of desktop power, with the added benefit of a decent webcam and a full-sized keyboard. If you're getting down to business on a budget, it's a great fit."
