The ASUS TUF Gaming A15 is very good for engineering and design, while the Lenovo Flex 5 14 is good.
The ASUS TUF Gaming A15's robust GPU alongside its quad-core CPU make it a powerhouse for engineering and design tasks, which demand more graphical and processing capabilities, but it's heavier and less portable compared to the Lenovo Flex 5 14. The Lenovo Flex 5, on the other hand, offers a touchscreen with a higher resolution and aspect ratio, useful for detail-oriented work in design, and its convertible nature enhances portability and versatility for different working environments.

The ASUS TUF Gaming A15 has a better screen than the Lenovo Flex 5 14 for general use, gaming and AI, engineering and design, and content creation.
If you prioritize a vibrant and sharp display for everyday tasks, the ASUS TUF Gaming A15's panel provides clear and bright visuals suitable for general use. For engineering and design work, both laptops offer decent color accuracy, but neither excels in covering the wide color gamuts professionals often need. However, gamers and those involved in 3D work may find the ASUS's lower refresh rate less than ideal compared to models specifically designed for those purposes, where smoother motion and faster screen updates are key.

How the ASUS TUF Gaming A15 and the Lenovo Flex 5 14 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 highlight of the latest IdeaPad Flex 5 14 is clearly its AMD CPU. The octa-core Ryzen 7 5700U is insanely fast even when compared to the best Tiger Lake Ultrabooks in the market or even Core H CPUs in many gaming laptops. It's a lot of raw processing power for what is supposed to be a budget 14-inch convertible. If your daily workloads can benefit from extra multi-thread CPU performance, then look no further than the inexpensive AMD-powered Lenovo IdeaPad Flex 5 14. For regular on-the-road browsing or video streaming, however, a slimmer and lighter 10th gen Core Yoga, Spectre, or XPS would be a more balanced option."
