The Lenovo Slim Pro 7 14 is very good for general use, while the Dell Inspiron 14 7420 is good.
The Lenovo Slim Pro 7 14 stands out for its superior AMD processor paired with a dedicated Nvidia graphics card, leading to better performance and an excellent screen with a higher resolution and refresh rate, enhancing your visual experience. On the other hand, the Dell Inspiron 14 7420 provides decent general use capabilities with an Intel processor and integrated graphics, yet it cannot match the Lenovo's longer battery life and slightly lighter weight for better portability.

The Lenovo Slim Pro 7 14 is good for engineering and design, while the Dell Inspiron 14 7420 is only fair.
The Dell Inspiron 14 7420 is well-suited for engineering and design use with a powerful Intel CPU and integrated graphics that support casual design work on its quality IPS screen; however, the Lenovo Slim Pro 7 14 excels further with an AMD CPU and a dedicated Nvidia GPU, making it superior for more graphically intensive engineering tasks and offering a higher resolution and brighter display, which enhances visual clarity and color accuracy. While both laptops have similar RAM for multitasking, the Lenovo's better graphics capability and screen quality come at the expense of a slightly higher weight that may affect portability in comparison to the Dell model.

The Lenovo Slim Pro 7 14 has a better screen than the Dell Inspiron 14 7420 for general use, gaming and AI, engineering and design, content creation, and software development.
The Dell Inspiron 14 7420, with its adequate resolution and brightness, provides a satisfactory display for everyday tasks like browsing and document editing but lacks the color accuracy and range required for precise engineering and design work. The Lenovo Slim Pro 7 14 offers higher resolution and brightness, making for a crisper and more vibrant screen suitable for detailed engineering applications that involve color-critical tasks. However, both models don't meet the mark for gaming and 3D applications due to lower refresh rates, which can result in less smooth motion and graphics during intensive visual activities.

"Notable qualities of the Inspiron 7420 2-in-1 include the 16:10 aspect ratio, strong hinges, 12th gen Intel CPU with optional GeForce MX graphics, and easy serviceability. Such features would typically cost hundreds of dollars more on higher-end alternatives from competing manufacturers. The value proposition is therefore relatively high for users looking to maximize bang for the buck."

"The Lenovo Slim Pro 7 is an attractive, portable laptop that’s ideal if you need a combination of CPU and GPU performance. It also nails the fundamentals with solid connectivity, an enjoyable keyboard, a large touchpad, and top-notch webcam. Display quality is a weakness, but it’s an acceptable compromise for the laptop’s extremely competitive $1,199 MSRP. The Slim Pro 7 is a versatile, affordable laptop and hard to beat for the price."
