My answer would be yes, Dropbox syncing seems much faster than iCloud syncing using CloudKit.
But, before switching to Dropbox I’d rather know several opinions of DevonThink staff and experienced users.
Just a simple example of my own experience : when I send a 20-minute YouTube URL (bookmark) to a DT database syncing with Dropbox, it’s fast. After sending the very same bookmark to a DT database syncing with iCloud, I have to wait much longer in order to see my bookmark in my DT database Inbox.
This is extremely time-consuming when you send several YouTube bookmarks to DevonThink.
Please note I always see that my recently sent bookmark has actually been uploaded to iCloud or Dropbox before leaving my device. I need to make sure the bookmark has been sent to the remote location and actually synced to the desired “Cloud”.
Please let me know your suggestions. Are you experiencing a significant sync speed difference between Dropbox and iCloud?
