The Dell Inspiron 16 5620 offers more storage, better performance for engineering tasks, and a larger screen which is beneficial for multitasking and productivity. However, it's heavier, which impacts its portability. The Lenovo IdeaPad 3 14" has a smaller footprint, making it easier to carry around, and boasts a longer battery life, making it suitable for on-the-go usage. Both laptops are similarly priced, so the decision comes down to whether you prioritize a larger screen and better engineering performance (Dell) or better portability and battery life (Lenovo).

"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 low-priced IdeaPad 3 14 delivers on core functionality. Lenovo's IdeaPad 3 14 meets all the basic requirements for an inexpensive office laptop. The matte IPS display is bright enough, the performance is high for the class, and the input devices are rock solid. In addition, the mostly quiet operation including the useful performance modes, cool surface temperatures, easy maintainability as well as expandable working and mass storage all contribute to the IdeaPad 3 14's value proposition."
