Finding the best iPad Office app

I've been searching for a good all around Office app for my iPad.  And so far there's a lot of "good enough" apps, but none particularly good one.

QuickOffice Pro HD seems nice for it's strong online storage support, until I found out that the experience of inserting image in documents was pretty terrible.  It is still by far the best for format support, but the moment you put image into the picture, suddenly the app becomes less than stellar.

Document To Go Premium also seemed ok on the first galance, but then the UI seems clumsy compare with QuickOffice.  It has less cloud storage support, less Office file format support (no Excel 2010 for instance).  Someone in review said it right: Document To Go does better on PowerPoint, while QuickOffice does better on Word.

Office2 HD seems cheaper and have a OK set of feature, but reviews were terrible.  And again, doesn't support enough file formats.

So basically, I am now back to square one.  I need to take a look at Apple's Page, KeyNotes and Number and see if they are strong enough the candidates.
