Choosing between the Dell Inspiron 16 5620 and the Lenovo ThinkPad Z13 depends on your preferences and needs. The Inspiron typically costs less, making it appealing if budget is a concern, and its larger screen makes it suitable for tasks that benefit from more screen real estate. However, it's heavier and has a slightly shorter battery life compared to the ThinkPad Z13. The ThinkPad Z13 offers a touch screen and a lighter, more compact design, enhancing its portability. Additionally, the ThinkPad Z13 has a higher battery life on average, making it better for on-the-go use. If prices are close and portability and battery life are important to you, the ThinkPad may be the better option. On the other hand, if you prefer a larger screen and don't mind extra weight, you may opt for the Inspiron 16 5620. Both laptops have identical storage and memory, and similar main processors, although the ThinkPad's AMD processor is complemented by a slightly stronger integrated graphics unit which could be beneficial for certain tasks.

The Lenovo ThinkPad Z13 and Dell Inspiron 16 5620 are both good for engineering and design.
The Dell Inspiron 16 5620 with a 16-inch screen, an Intel CPU and integrated GPU, is well-suited for engineering because of its ample screen estate for design work but is less portable due to its size and weight. Conversely, the Lenovo ThinkPad Z13, though offering greater portability with a lighter and more compact form, also packs substantial power with an AMD CPU and GPU, and impresses with higher screen quality, making it a strong contender for on-the-go engineering tasks.

"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)."

"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."
