With either Evernote Business or OneNote used with SharePoint or SkyDrive Pro, business data belongs to the employer and stays under the control of the IT admin. If a user leaves a company, he or she no longer has access to the company notebooks and data, but retains access to their personal notes.
If an Office 365 subscription lapses, the locally installed OneNote software reverts to read-only mode. However, the data still exists through SkyDrive, and you can still use OneNote by way of its Web or mobile apps.
All three services clearly state that you own your data. This offers little consolation, though, if the company goes out of business or shuts the service down.
Winner: A tie. All three services provide roughly the same assurances of data ownership, but no means of exporting or archiving your data.
Google Keep, Microsoft OneNote, and Evernote each offer distinctive benefits. Unless you're Google-focused or Microsoft-centric, however, Evernote is the most diverse and capable service.
Google Keep is nice and simple, but its capabilities are extremely limited.
OneNote is an exceptional product, and comes in a close second to Evernote. Although OneNote is available for a variety of platforms and devices, it's still a Microsoft tool, so it lacks the platform-agnostic approach and strong third-party support that strengthen Evernote.
Evernote provides users with a powerful note-taking platform for free, along with customization and expanded capabilities through apps and add-ons. Plus, Evernote's version for businesses is straightforward and affordable.
