The Dell Inspiron 16 5620 is more budget-friendly and provides a good balance for general use with a decent battery life. It's relatively portable and offers silent operation. However, if you need higher performance for tasks like 3D rendering, machine learning, or engineering software, the Lenovo ThinkPad Z16, while more expensive, has a significantly better screen, more power under the hood, and additional features like a touchscreen, fingerprint reader, and facial recognition. The ThinkPad Z16's OLED display will also be more vibrant and is better for color-sensitive work, but this comes at the cost of a slightly lower battery life and portability. Give Feedback

The Lenovo ThinkPad Z16 has a better screen than the Dell Inspiron 16 5620 for general use, gaming and AI, engineering and design, content creation, and software development.
For general use, the very good screen quality of the Lenovo ThinkPad Z16 can be attributed to its high-resolution panel providing sharp visuals and excellent brightness ensuring good visibility in various lighting conditions, which outperforms the fair screen quality of the Dell Inspiron 16 5620. When it comes to engineering and design, the ThinkPad Z16 offers excellent quality due to its wide color gamuts, delivering precise color reproduction necessary for professional design work, whereas the Inspiron's fair quality may lack that color accuracy and range. However, for gaming and 3D applications where refresh rate is crucial for smooth motion, both laptops fall short with poor screen quality as they do not prioritize high refresh rates which are essential for these activities.

"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)."

"Lenovo’s ThinkPad Z16 tries has some success in its effort to tweak the ThinkPad formula. The laptop is attractive, yet still tame, and material quality is on par with the best Windows competition. I also like the smooth, responsive haptic touchpad and the wide range of modern connectivity. Yet the Z16 doesn’t fix ThinkPad’s typical weakness: value. Starting around $1,550, and more typically near $1,700, the Z16 finds itself facing alternatives that have better performance or an improved display for the same price, or less."
