Not the answer you are looking for but this is perfectionism at play. Use anything you like well enough and seek out the task to solve instead. These are tools, you can sharpen them to work better but cutting is the task not just sharpening all the time.

Linux with AMD graphics is much more stable than with nvidia.

I have also counterintuitivly found Arch Linux (a rolling release distro) way more stable than Ubuntu LTS. Things like sleep works, and any bugs are small and fixed quickly, bug reports are followed up on within a couple of days. With Ubuntu bug reports go without any replies from the maintainers, and maybe it will be fixed by happenstance by the next release.
