If you prioritize a larger screen and slightly better storage, the Dell Inspiron 16 5635 would be suitable, especially if a lower price is important to you. However, it's bulkier and heavier, which may impact portability. On the other hand, the Lenovo ThinkPad Z13 offers a more compact and lightweight option with a superior build quality, a better keyboard, and longer battery life, making it more portable and well-suited for business use, although it has less storage and costs a bit more. If touchscreen capability, facial recognition, and a higher quality display are important to you, the Lenovo would be the better option. Give Feedback

The Lenovo ThinkPad Z13 and Dell Inspiron 16 5635 are both only fair for gaming and AI.
The Dell Inspiron 16 5635's integrated Vega 8 graphics in its AMD Ryzen processor offer modest gaming performance but are limited for demanding 3D tasks, complemented by a standard 60Hz refresh rate screen which is adequate for casual gaming but not ideal for fast-paced or competitive games. On the other hand, the Lenovo ThinkPad Z13 also has integrated graphics, specifically the AMD Radeon 680M, which provide similar gaming performance with the same 60Hz screen refresh rate, but its smaller screen and slightly higher pixel density mean a sharper but smaller display for gaming and 3D applications.

The Dell Inspiron 16 5635 and Lenovo ThinkPad Z13 are both good for engineering and design.
The Dell Inspiron 16 5635 is equipped with an AMD Ryzen 7 CPU and Vega 8 GPU, combined with a 16-inch IPS screen of high resolution, making it well-suited for engineering and design tasks that require a large, quality display and capable processing power. Meanwhile, the Lenovo ThinkPad Z13 offers a similarly powerful AMD Ryzen 7 CPU with a Radeon 680M GPU, but stands out with its smaller, highly portable design and touch-enabled, high brightness & color-accurate 13.3-inch screen, favored for on-the-go productivity and detail-oriented work.

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."

"In the premium ultraportable space, the Lenovo ThinkPad Z13 competes with the best of the best, and still manages to shine. The design is an impressive departure from the bland bare-metal laptop that's become so popular in recent years, and the AMD-powered system has performance that's just as impressive. It's a stark alternative to the Intel-based majority, and it stands up well enough to the impressive Apple M2 processor."
