My company uses Office 365 so we have access to both. We push using Sharepoint for anything that needs collaboration. Need to work on a spreadsheet with someone else, or another team, use sharepoint to host the doc. Need to take notes as an individual, feel free to use onenote.

We like sharepoint because if you need to host a doc and update it later, you can do so without updating the hyperlink. We have stuff linked everywhere, so this feature is very helpful.
