The OP will get his reward in heaven for such an excellent and thorough comparison. Thanks so much.
Unless I missed it (and I scanned the review only briefly), the only aspect of the review that I would like to see added involves importing the three Apple apps into their Microsoft Office counterparts.
Since it's clear from the review that Pages, Numbers, and Keynote are superior to the simulated Office alternatives for working with Office documents, the question arises as to whether iPad created documents are fully compatible with the Office applications. I mention this mainly because it's my impression that the iPad versions of Pages, Numbers, and Keynote have reduced functionality compared to the versions Apple sells for their "real" computers. That in turn suggests that Msoft Office might react somewhat differently to documents created with those applications on the iPad.
