If you prioritize a higher performance level for tasks like intensive engineering work, video editing, or gaming, the HP Spectre x360 is a stronger option with a more powerful processor. However, you'll spend more and it's slightly heavier, which may affect portability. The Dell Inspiron 15 3511 is more affordable and lighter, making it easier to carry around, but it has lower performance capabilities. The Spectre x360 also has a higher resolution screen that may be beneficial for detailed visual work, but it could reduce battery life faster than the Inspiron's display. Consider what is more important to you: affordability and portability or performance and high-resolution display. 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."

"As we said, Lenovo's Yoga 9i is a tough competitor to the Spectre with an equally admirable OLED display. We're sad that neither of them has an HDMI port nor a niche or slot to hold the stylus, though the HP wins points for its bundled mini docking station and magnetically attached pen. Your choice will come down to screen shape—and in our eyes, just as seeing an OLED screen spoils you for an IPS panel, enjoying a tall 3:2 display spoils you for a more conventional view. The HP Spectre x360 13.5 is our new favorite 2-in-1."
