As much more educated gents than me have pointed out, the amount of room treatment needed can vary a great deal by speaker, so the idea that one way or the other is more correct is not well supported.
Controlled narrow directivity can greatly enhance imaging and detail, reducing the need for room treatment. Line arrays, horns and panels (ESLs) can really help.
But a well treated room can take any of them and make them sound spectacular. A poor room will be much more speaker dependent.
The buyer's own preferences matter a great deal. Personally, I have to use a half and half approach. I used tweets with narrow dispersion, and add bass traps and room treatment.
