The Dell XPS 15 and Lenovo Slim Pro 7 14 are similarly priced, but designed for different users. The Dell offers a larger 15-inch screen, a slightly bigger battery, and may perform better for general tasks. It’s heavier, which impacts portability, but has a higher-built quality and better heat management. The Lenovo, on the other hand, comes with a higher resolution touchscreen, is lighter, and has longer battery life, making it more suitable for on-the-go use. Its more powerful graphics card is better for 3D tasks, machine learning, or light gaming. Both have ample storage and memory, but your choice should depend on whether you value a larger display and sturdier build or better portability and graphics performance. Give Feedback

"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."
