The Dell Inspiron 14 7435 is typically less expensive and offers good portability paired with decent battery life for everyday use; its processor and graphics are suitable for general tasks and moderate multitasking. However, the Lenovo Legion Slim 7 16" is more expensive, has better performance capabilities for 3D rendering, machine learning, and engineering software, and it boasts superior screen color coverage and refresh rate, making it ideal for intensive gaming and creative work. Its battery capacity is higher, but its larger size and weight make it less portable than the Dell. Consider the Lenovo if performance in demanding applications is a priority and the Dell for portability and savings. Give Feedback

The Lenovo Legion Slim 7 has a better screen than the Dell Inpsiron 14 7435 for general use, gaming and AI, engineering and design, content creation, and software development.
The Dell Inspiron 14 7435 has a screen that's fine for everyday tasks and office work due to its adequate resolution and brightness, but it falls short for engineering and design due to limited color gamut coverage, which is crucial for color accuracy.

However, despite their respective strengths in other areas, both laptops aren't ideal for gaming and 3D purposes because they lack the high refresh rates that are key for smooth visuals in fast-paced scenarios.

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."

"The Lenovo Legion Slim 7 is a slim Legion notebook that is just as excellent with Nvidia & Intel. However, the Legion Slim 7i slightly sullied by lacklustre battery life. You get a slim aluminium chassis, great input devices, decent port selection, fast high-quality WQXGA display and great performance. Supporting Thunderbolt 4 is one advantage of the Intel/Nvidia model tested in this review. Moreover, this variant has slightly higher CPU performance as well as better GPU performance in certain applications (e.g. CUDA-based apps). The Lenovo Legion S7i is thin, premium and performant – but less efficient than its AMD counterpart."
