If you require a laptop mainly for general use with solid performance and portability, the Dell Inspiron 14 Plus could be suitable due to its compact size and balanced features. However, if your focus is on gaming, 3D tasks, or machine learning, then the Lenovo Legion Slim 7 16" offers higher performance capabilities and a larger screen, which may better suit your needs, albeit at the expense of reduced portability and potentially shorter battery life due to its more powerful components. Keep in mind that higher performance often comes with a higher price tag, so the Lenovo might be the pricier option. Give Feedback

The Lenovo Legion Slim 7 has a better screen than the Dell Inspiron 14 Plus for general use, gaming and AI, engineering and design, content creation, and software development.
The Dell Inspiron 14 Plus is equipped with a display that offers satisfactory resolution and brightness for general productivity tasks and is suitable for engineering and design due to its decent color accuracy; however, its lower refresh rate is not ideal for the fast-paced visuals required in gaming and 3D applications. The Lenovo Legion Slim 7 16" stands out with its high-resolution display and brighter screen, offering a crisp and vivid visual experience for both general use and detailed engineering work, as well as capable color reproduction, but like the Dell, it lags behind in refresh rate, which is critical for the smooth rendering of 3D graphics and gaming content. Both laptops prioritize factors such as resolution, brightness, and color over the higher refresh rates that are necessary for gaming and designing in 3D environments.

Although they have very similar scores, PerfectRec considers Lenovo Legion Slim 7 16" to be very good for general use, while the Dell Inspiron 14 Plus is good.
The Lenovo Legion Slim 7 with its higher-tier graphics and larger, brighter screen, along with a considerably larger battery, likely exceeds in general use performance and visual experience compared to the Dell Inspiron 14 Plus, which, while still capable with a solid CPU and sufficient RAM, offers less screen real estate and lower maximum brightness, but could be more portable due to its smaller size and lower weight.

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."
