The Dell Inspiron 14 Plus is a good choice if you're looking for a more portable device with a higher resolution and a slightly larger battery capacity, suitable for general use and some lighter engineering tasks. It has an Intel processor with integrated graphics, making it less suited for gaming compared to the Lenovo. On the other hand, the Lenovo Legion Slim 7 offers superior gaming performance due to its dedicated Nvidia graphics card, and is great for more demanding engineering and 3D/machine learning tasks. However, it's somewhat heavier, which might impact its portability, and it also generally costs more. Both laptops have the same amount of RAM and storage, but the Dell tends to be less expensive and has a slightly longer battery life for typical use. Give Feedback

The Lenovo Legion Slim 7 15.6" is good for gaming and AI, while the Dell Inspiron 14 Plus is only fair.
The Dell Inspiron 14 Plus is suitable for gaming and 3D tasks due to its high-resolution IPS screen and capable integrated graphics, but with a standard screen refresh rate it may not be as fluid for fast-paced gaming as other options. In contrast, the Lenovo Legion Slim 7 boasts a powerful Nvidia RTX 3060 GPU and a higher screen refresh rate, making it better for gaming experiences that demand quick visual responses, though its standard full HD resolution may not be as sharp as the Dell's display.

Allen Ngo | August 2022
"The Dell Inspiron 14 Plus is for power users on a budget. If you're looking to maximize CPU and GPU performance on your next 14-inch laptop, then consider the pricier Razer Blade 14 or Asus Zephyrus G14. If you're looking for a thin-and-light 14-inch Ultrabook, then the Asus Zenbook 14 or LG Gram 14 may be better options. For the best of both worlds, however, the Dell Inspiron 14 Plus 7420 rides a fine line between extreme performance and portability while keeping prices at reasonable levels. Frequent travelers who rely on performance beyond what the Core U-series and integrated graphics series can offer will find the Dell to be a solid solution."

"The Lenovo Legion Slim 7 is a slim Legion notebook that is just as excellent with Nvidia & Intel. However, the Legion Slim 7i slightly sullied by lacklustre battery life. You get a slim aluminium chassis, great input devices, decent port selection, fast high-quality WQXGA display and great performance. Supporting Thunderbolt 4 is one advantage of the Intel/Nvidia model tested in this review. Moreover, this variant has slightly higher CPU performance as well as better GPU performance in certain applications (e.g. CUDA-based apps). The Lenovo Legion S7i is thin, premium and performant – but less efficient than its AMD counterpart."
