The ASUS TUF Gaming A15 is very good for engineering and design, while the Lenovo IdeaPad Slim 5i is good.
The ASUS TUF Gaming A15 is superior for engineering and design due to its more powerful AMD Ryzen 7 processor and Nvidia RTX 4070 GPU, which offer robust performance for demanding tasks, but it's heavier and less portable than the Lenovo IdeaPad Slim 5i, which has an adequate Intel i5 processor and integrated graphics that suffice for less intensive engineering applications and has a higher portability with a lighter frame and better keyboard quality. The ASUS also stands out with a higher refresh rate display and more storage capacity, while the Lenovo provides a slightly better screen resolution and aspect ratio for more vertical screen real estate.

How the ASUS TUF Gaming A15 and the Lenovo IdeaPad Slim 5i compare to other laptops
"With the release of the TUF Gaming A15, Asos have concentrated on the essentials: gaming performance. Our base version, which can be had for around $1,169, already provided enough power to play current games smoothly in a native resolution of 1080p and with maximum details - thanks to its new Nvidia GeForce RTX 4050 Laptop. If you utilize upscaling, then you can even manage to run ray tracing."
"The device is made for average work loads and if your work has a lot to do with online browsing, using apps that are not power-hungry and streaming videos. The looks are really good and the device in itself is not a heavy one. And with Intel 11th-gen Core processor, you might sail through most of your work without complaints."
