The Dropbox SDK is MUCH better and more mature than the Box SDK. Dropbox bases its interactions on the paths of files/folders while Box bases it on the unique ID of the item. Converting a path to an ID in box is a very expensive operation that requires you to recursively list the root and then each ancestor folder up to the item. As another example, the Box authentication view controller on iOS has no real support for a cancel button. The web page displayed by it includes it's own faux toolbar at the top, which interferes visually with providing your own.
