The Dell Inspiron 14 7435 is more expensive but offers higher performance with better processing power and more memory, making it suitable for more intensive tasks such as engineering work and light gaming. It also has better portability because of its smaller size and slightly lighter weight. The Lenovo IdeaPad Slim 3, while more affordable and with a larger screen, has less memory and a lower tier processor, making it more fitting for general use and not as suitable for demanding applications. Both have good battery life, but the Lenovo edges out slightly in this aspect and may be a better choice if you prioritize longer usage on a single charge and cost-effectiveness over power and performance.

The Dell Inpsiron 14 7435 has a better screen than the Lenovo IdeaPad Slim 3 for software development, and content creation, while the Lenovo IdeaPad Slim 3 has a better screen for general use, and engineering and design.
The Dell Inspiron and Lenovo IdeaPad both have displays that meet the basic requirements for general tasks like web browsing and document editing, meaning their resolution and brightness suffice for average users, and their panel types are good enough for comfortable viewing. However, for engineering and design where precise color representation is crucial, these laptops lack wide color gamuts, making them less ideal for these professions. For gaming and 3D applications, the lower refresh rates on these models may lead to less fluid visuals, thus diminishing the gaming or 3D rendering experience.

Although they have very similar scores, PerfectRec considers Dell Inpsiron 14 7435 to be only fair for gaming and AI, while the Lenovo IdeaPad Slim 3 is poor.
The Dell Inspiron 14 7435 is fair for gaming and 3D because it has a more powerful GPU (AMD Vega 8) and a stronger CPU, which are important for performance, but its 60Hz screen limits the smoothness of fast-paced visuals. The Lenovo IdeaPad Slim 3 also offers fair performance for gaming and 3D due to its decent GPU (AMD Vega 6) and CPU, but similarly, it is restrained by a 60Hz screen, resulting in less fluid motion during gameplay or 3D applications.

PCMag
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 IdeaPad 3i is decent for use as a workstation. Its Intel CPU and integrated graphics can only handle light productivity tasks, not demanding workloads like video editing or 3D graphics. You also can't do any color-critical work because the available displays have a narrow color gamut. It has a good port selection, but its USB-C lacks Thunderbolt 4 support. On the upside, it has a comfortable keyboard and doesn't get hot or loud under load."
