Insync
Insync
Insync is a feature rich Google Drive client for Windows, Mac and Linux. The ability to sync and manage Google Drive files for multiple accounts and automatically convert files to Microsoft Office or OpenDocument are fantastic and make Insync perhaps the best Google Drive desktop client available today. Certainly worth the one time payment for those features alone. The added feature of it supporting OneDrive in the near future will make it worth looking into when it is added.

Syncthing
Syncthing
Syncthing is a great open source product that delivers what it intends to, free, open source syncing across multiple computers and platforms. It works well but it does have some challenges including not being as easy to use as many of the non-open source alternatives. Where it does shine is when you need an easy to use sync service for multiple computers running different operating systems.
