For a balance of performance and price, the Lenovo LOQ 16i is a strong contender with its newer i7 processor and dedicated Nvidia RTX 4050 graphics, making it suitable for gaming and machine learning tasks. It also offers a larger 16-inch display with a higher refresh rate, which is beneficial for smoother visuals. However, it's slightly heavier and pricier than the Dell Inspiron 15 3511. The Dell, on the other hand, is more budget-friendly and portable, with a smaller 15.6-inch screen and lighter design, but it compromises on performance and screen quality, making it better suited for general use rather than intensive tasks. Consider the Lenovo for better performance and screen quality if you're willing to carry a bit more weight and spend a bit more, but choose the Dell for its portability and lower price point for everyday tasks.

PCMag
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."

"Gaming laptops with an RTX 4060 are available starting from about 1,000 Euros (~$1,060), even in 16-inch format. For the supposedly affordable Lenovo LOQ 16 (1,500 Euros, ~$1,591), the manufacturer particularly saves in the equipment and materials compared to the more expensive Legion series. In addition, the LOQ is slightly heavier and more bulky. What remains is anything but a laptop full of difficult compromises. Instead, this is a more than solid gaming laptop that focusses on the 3D performance.Q is slightly heavier and more bulky."
