I tried it out on a scan of a 57-year-old newspaper page that I'd found in my attic, and Acrobat let me add text that almost no one could tell hadn't been typeset and printed in 1958. However, it was difficult to click in the correct text box to edit in such a document, because you may see multiple, overlapping boxes. And when I tried to use Edit PDF on a couple of recent store receipts containing very clear, monospaced-font text, Acrobat made very little of the text editable. If you don't like the result, you can't undo, either--you have to close the document and start over.
Adobe has created a very useful cloud service, albeit one that's segregated from other cloud services, but the integration of electronic signature sending and tracking is the thing that sets it apart from other PDF applications. If you don't need signing but you still need Acrobat for other functions, then you might consider using the perpetual version with the cloud service of your choice.
