I work in the public sector, we’re not allowed to use Chinese hardware and we get a special version of Windows 10 that has had it’s tracking disabled by Microsoft and verified/reviewed by our version of the NSA.

The only smartphones we’re allowed to use are iPhones that are enrolled into our enterprise program.

I can’t tell you if that means Apple tracks you less than Lenovo or Microsoft, but you can be pretty sure that someone is tracking you if you use unmodified hardware/software.
