There seem to me to be at least two such characteristics. They are: its
facility to allow "chunks" of text to be quickly and easily re-arranged
within the whole, and its feature enabling relatively straightforward
export or "compilation" of the text in a wide variety of styles and
formats. Those two features make it particularly attractive if you're
engaged in writing medium- or long-form work (and these plainly provide
reasons for novelist David Hewson's fondness for it). And it has other
features which also support this type of writing.

That is true. Ulysses is best compared with writing (word processing) applications like Scrivener while Notebooks more comparable to noting applications like nvALT, and Tinderbox. If you want to get a finished product, Notebooks might not be the right one.
