I also tend to keep iCloud services away from my Windows laptop. I do have the Apple Music and Apple TV beta apps installed on Windows laptop but no other Apple software. I haven't tried iCloud software recently but have had issues with it in the past so just use the website or my phone if my Mac is not around.
Conversely, on the Mac, I have had Microsoft Office 365 installed and OneDrive for many years. There were some issues with OneDrive particularly around a MacOS update that broke all cloud drive services at the time. Once an update from Microsoft came out, it was solid again for me. I haven't used OneDrive in the past 12 months or so but thats for work reasons not any issue with the software/service.
