I asked which is best a couple of days ago. Now I know, so I'm posting my experience for others.
I tried the apps DataCase and Files and read about FileMagnet. Files comes out best in several ways
1. With Files the directory structure is preserved and navigable on the touch/iphone. One can therefore easily mirror a tree of files on the mac and the touch/iphone - just drag and drop the tree and they will be in the same place on touch/iphone. A nice aspect of that is that files of different kinds that are together on the mac stay together on the touch/phone. With DataCase they appear in a "typed" global space - all images in one place, all docs in another etc. I am guessing, because of the way it works with a dedicated mac client that queues files for transfer, that FileMagnet also puts them in a global space.
2. Files gives more screen space because the controls auto-hide. I use it to look at map images and the extra space helps a lot.
3. Files uses webdav and therefore works with both Mac and Windows (and linux). I think that FileMagnet is mac-only (not tested). DataCase also can work with windows and linux.
4. With DataCase, if the app (and therefore the webdav server) is running, the touch/phone does not go to sleep - unless one manually "sleeps" it the screen remains on. Files operates with the normal screen-saver/sleep mechanism. The screen staying on will use more battery but seems to me to be a very minor point.
So Files therefore scores over both other apps on points 1 and 2, scores over FileMagnet on point 3. and scores over DataCase on point 4. I can find no way in which either DataCase or FileMagnet are better than Files (but note I did not test FileMagnet). If my guess that FileMagnet puts files in a global space is wrong then still Files scores over FileMagnet because it needs no dedicated client and also will work with other OS'es.
Summary:
Advantages of the Files app:
1. preserves navigable tree
2. more screen space
3. works with mac, windows, linux
4. works properly with sleeping
None of the others have all of these. In my view Files is clearly the best one of the three apps.
I hope this helps some people.
