The Dell Inspiron 14 7435 offers stronger performance and versatility as a 2-in-1 convertible than the Lenovo IdeaPad 3 15", making it suitable for more intensive tasks and providing the flexibility to use it as a tablet. The Dell also boasts a higher-quality screen and longer battery life, which enhances the overall user experience, especially for multimedia consumption and productivity. However, the Lenovo IdeaPad is lighter on the wallet and might be sufficient for basic tasks like web browsing, document editing, and casual use. If portability is a concern, Lenovo could be easier to carry around due to its lighter weight. Ultimately, the decision depends on your willingness to invest in higher performance and features versus looking for a cost-effective solution for general use. Give Feedback

The Dell Inpsiron 14 7435 is good for general use, while the Lenovo IdeaPad 3 15" is only fair.
The Dell Inspiron 14 7435 is considered good for general use due to its higher-end CPU, more RAM, superior AMD integrated graphics, better battery life, and higher-quality IPS screen with a 16:10 aspect ratio which is better for productivity. On the other hand, the Lenovo IdeaPad 3 15" is deemed fair because it has a lower-tier CPU, less RAM, lower quality TN screen with a 16:9 aspect ratio that has less vertical space, and inferior battery performance, despite being slightly better in portability due to its lower weight.

The Dell Inpsiron 14 7435 has a better screen than the Lenovo IdeaPad 3 15" for general use, gaming and AI, engineering and design, software development, and content creation.
When choosing between the Dell Inspiron 14 7435 and the Lenovo IdeaPad 3 15", the Dell's screen offers better resolution and brightness, which can make text and images sharper and easier to view, enhancing the experience for general use and detailed engineering work. For tasks requiring color accuracy, like engineering or design, the Dell's coverage of color gamuts may be more adequate, but neither are particularly well-suited for the high standards of these fields. Meanwhile, the Lenovo falls short in screen refresh rate, making it less ideal for 3D applications where smooth motion is crucial, and the same is true for the Dell but to a lesser extent due to its slightly better resolution and panel type.

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 3 is an enduring office notebook with a powerful Ryzen APU. Lenovo's office all-rounder easily handles office and internet applications as well as modest games - the Ryzen 5 5625U APU and 16 GB of RAM make this possible. The CPU and GPU can work at consistently high clock rates. The emission values are okay, but the noise emissions should be lower under medium to full load. The relatively light notebook (approx. 1.6 kg) achieves practical battery runtimes of about 10 to 11 hours."
