Let me start by acknowledging that iWork apps lack many of the more advanced features found in MS Office. Having said that, though, I think it's worth noting that iWork does many basic things much better than Office.
For starters, anyone who's any good with presentations will tell you that Keynote is vastly superior to PowerPoint. It's simply easier to use and makes it easier to create attractive and professional looking presentations.
Numbers lacks many of Excels' advanced features, but in many ways it's far easier to use than Excel for everyday tasks. As an example, Numbers lets you place multiple tables on the same page and independently resize rows and columns on each table. This is simply impossible in Excel. Also, in Numbers you can efficiently click, drag and drop rows, columns or cell selections while in Excel this requires less the efficient use of menus and cut/copy/paste functions.
Many tasks that are clunky, complex and unintuitive in Office, like trying to make an image's background transparent, are effortless and efficient in iWork.
Finally, you state that MS Office can guarantee formatting and functionality are retained when sharing docs. This is not quite true. This is only guaranteed when sharing the document with someone who has the exact same version of MS Office. You will often lose both formatting and functionality when opening a doc with an older version of MS Office (which many people have) or when sharing between Office on the desktop and Office on Windows RT or Windows Phone.
