If you're looking for more affordable options and don't mind a larger, heavier laptop, the Dell Inspiron might be suitable for everyday use and tasks that don't require high performance. On the other hand, if portability is a priority and you're willing to invest more for a sleeker design, the Lenovo ThinkBook could offer better ease of carrying with potentially improved build quality and performance suited for more demanding applications. Keep in mind, though, that the lighter laptop might have a smaller screen size, which could impact multitasking and media consumption. Give Feedback

Although they have very similar scores, PerfectRec considers Dell Inspiron 16 5635 to be very good for general use, while the Lenovo ThinkBook 13x is good.
The Dell Inspiron 16 5635 offers a robust CPU and ample RAM which is essential for smooth performance in a variety of tasks, along with a high-quality screen and a longer battery life, making it well-suited for general use while still being reasonably portable. The Lenovo ThinkBook 13x, with its compact form, also provides a good quality screen and keyboard, lower operating noise, and effective heat management, but the smaller screen size and potentially shorter battery life compared to the Dell make it more of a balance between portability and user comfort.

UltrabookReview
Derek Sullivan | January 2023
"Compared to the previous year’s Inspiron, Dell upgraded the screen aspect ratio on this generation, but also transitioned to a more minimalistic centered keyboard flanked by up-firing speakers. The 16-inch screen is huge plus and I really appreciate the extra real estate without sacrificing the footprint much. This year’s model is a little larger than last, though, as the former model was already very small for a 15 incher."
