If performance in general use or engineering is your priority, the Dell Inspiron 16 5620 offers comparable computing power and a larger number of total display outputs. However, the Lenovo IdeaPad Slim 5i boasts a newer processor, potentially firmer build quality, better-perceived keyboard quality, and more USB-C ports, which might make it a better option for those seeking modern connectivity and typing experience. Both laptops are similarly priced, provide ample storage and memory, and neither is designed for intensive gaming. Battery life is similar, but if screen brightness is important for you, the Lenovo offers a brighter display, which could enhance visibility in well-lit environments. Both laptops come with Windows 11 and are equipped with a backlit keyboard and a fingerprint reader for added security but note the Dell's additional number pad which can be crucial for data entry tasks.

The Dell Inspiron 16 5620 has a better screen than the Lenovo IdeaPad Slim 5i for content creation, while the Lenovo IdeaPad Slim 5i has a better screen for general use, and engineering and design.
For general use, screen quality is often gauged by clarity and visibility which both the Dell Inspiron 16 5620 and Lenovo IdeaPad Slim 5i offer with their respectable resolution and brightness, but they aren't top-tier in these aspects. In engineering and design, accurate color representation is key, and while these laptops provide a decent range of colors, they don't cover the professional color gamuts extensively, so they are suitable for entry-level work but not for high-end professional tasks. When it comes to gaming and 3D applications, the refresh rate becomes crucial for smooth visuals, and both laptops lack in this department, making them less ideal for serious gaming or advanced 3D work which would benefit from a higher refresh rate.

"If the world is exciting enough right now, you can do far worse than a solid performer that you know will get the job done. Our review model is as powerful as you'd want an office machine to be unless you're performing specialist tasks and the price point is pretty attractive (unless work will let you have a MacBook Air instead)."

"The device is made for average work loads and if your work has a lot to do with online browsing, using apps that are not power-hungry and streaming videos. The looks are really good and the device in itself is not a heavy one. And with Intel 11th-gen Core processor, you might sail through most of your work without complaints."
