I am assuming the target market for this is European short haul flights?

On something like a New York <-> Los Angeles flight I cannot imagine the turboprop beats a 737 in any performance or comfort category.

The article is not about turboprop but about open-rotor engines which are a modern variation of propfan engines.

Since you've undertaken the effort of distinguishing, please elucidate the difference in your own understanding of it, (and not whose brand or publication name is validating the terminology) in more detail.
