Again, I am not debating "quality" nor "architect technical skills" but rather "artistry" and "attention to details."
Think of P+S as the GMC of the architecture profession--they can do everything just not exceptionally nor interestingly--comparing GMC cars to BMWs or Audis.
P+S and some others are like this: I gots a piece of land. Design me a box to put on it so I can get the marketing crew to sell it.
Or you could do the same and put a funky geometric pattern on the box and get a boutique designer to "style" it. That's where aA, Teeple etc come into play.
