I personally witnessed two lenovo legion laptops bought at the same time have pretty severe issues. One had a USB port fail, and the other seemed to have an issue with the SSD controller where it would flake out every 30 minutes causing a complete system crash, even after replacing ram and SSD.

They were both the same model, so maybe there was something specific to that, but considering bow much they cost and yet only lasted a year before encountering issues, desktops seem the safer long-term bet.
