I disagree. While it is true that it is more expensive per GB, Dropbox has a lot of features that make it more fit for heavy lifting, such as:<p>* Chunked uploads. Try to modify a 1GB file in OneDrive. The complete file will be resynchronized. Dropbox just uploads the chunks that have changed.<p>* LAN sync. If you are sharing files with family&#x2F;colleagues that are on the same network, Dropbox shares file chunks peer to peer. This usually results in much faster synchronisation than downloading from the cloud.<p>* Dropbox has file requests. People can upload files to your Dropbox, but what others upload is not visible.<p>* In my experience, the Dropbox client is a lot more stable than the OneDrive client on OS X. OneDrive crashes or sometimes cannot sync certain files.<p><i>To me</i> the speediness, file requests, and more reliability is well worth whatever the price delta is.<p>(Note: I have both, but I only use OneDrive as an endpoint for Arq backups.)
