The ASUS TUF Dash 15 is a more budget-friendly option with a focus on gaming, offering a larger screen, a high refresh rate, good heat management, and includes features like hardware ray tracing. It's also slightly heavier and thicker than its competitor, making it less portable. The Lenovo Slim Pro 9i, on the other hand, is a premium laptop with a smaller but higher resolution Mini LED touchscreen, greater color accuracy, more storage and memory, and emphasizes overall performance, suitable for engineering and creative work. However, it comes at a higher price and its battery may not last as long as the ASUS during typical usage. Both have backlit keyboards and multiple USB-C ports, but only the Lenovo offers facial recognition. Choose the ASUS if you want a gaming-oriented laptop that's more affordable, or the Lenovo if you're willing to invest in a higher-resolution touchscreen display and better performance for creative tasks.

"The Asus TUF Dash F15 FX517ZR is a laptop with mobile RTX 3070 and acceptable battery life. The Asus TUF Dash F15 was made for high-performance applications like video editing, rendering, and gaming. The laptop can manage the latter in QHD resolution and at high to maximum settings. However, the focus isn't on maximum performance, but instead, it's about a compromise between performance and portability."

"The Lenovo Slim Pro 9i is an impressive laptop with a brilliant Mini-LED display, a powerful 100-watt version of Nvidia RTX 4050 graphics, and excellent connectivity. Having run the Cinebench benchmark again, we were impressed with the CPU performance. That makes the Slim Pro 9i is an easy recommendation, especially for those who care about GPU and CPU performance. It’s also a fantastic choice if you frequently view HDR movies and games on your laptop."
