I have primarily used Linux for ~15 years. At this point I honestly believe that it's less painful to switch from Windows to Linux than the other way around.

It's obviously still painful to change habits. And I won't downplay how Linux can often be difficult to get working perfectly.

The problem with Windows is that it just feels downright user hostile. Ads here and there, MS products constantly pushed, wizards everywhere, taskbar icons for every piece of hardware. It's like you are renting your PC instead of owning it.
