I'm judging my experience on my experience.
But of the two problems I've experienced in my first 5 months of owning the most luxurious and expensive laptop out there:

I'm going to go out on a late-night limb here and say that to a certain extent you may have to bear some responsibility for these issues. You bought a £3k laptop and your USB 2.0 mouse didn't work with it. Why not just change your mouse? Or buy an apple trackpad and bathe in its awesomeness.
And then you install the very first version of a new OS which has been designed primarily for the Apple M1 SOC. Yes, it shouldn't brick your machine but you didn't need to upgrade, certainly not before checking if there were going to be issues.
Both Windows and Linux offer far more stable and predictable experiences with more longevity and productivity than Apple.
God knows I'm livid with Apple for their T2 chip (edit: and Bog Sur bypassing the firewall) but I can't quite agree with this; in fact it's the reason I'm still with OSX despite Apple being dicks about dropping support for Nvidia GPUs and Linux.
