The Lenovo ThinkPad Z13 has a better screen than the Dell Inpsiron 14 7435 for general use, gaming and AI, engineering and design, and content creation.
The Dell Inspiron 14 7435 offers a display that is sufficient for daily tasks and some professional work with its resolution and brightness, although it lacks the wider color gamut needed for precise color work in engineering and design. The Lenovo ThinkPad Z13, with its higher resolution and brightness, provides a sharper and more vibrant screen suitable for both general use and color-sensitive tasks, benefiting from a wider color spectrum. However, for gaming and 3D applications where fast refresh rates are crucial, neither laptop is ideal due to their lower refresh rates which can lead to less smooth visuals in fast-paced scenes.

Eric Grevstad | August 2023
"We see no shame in an economy laptop missing the four-star mark. Frankly, we considered giving the Inspiron 14 2-in-1 three-and-a-half stars for its low price, competitive performance, and long battery life. Unfortunately, working with a screen that can't deliver at least 300 nits of brightness is simply no fun to the point of detrimental. Still, if you're looking for a convertible laptop on a tight budget, it's worth keeping an eye on Dell's sales and discounts. That Lavender Blue model is fairly tempting."

"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."
