I agree almost completely with this. When I used to play a lot of acoustic pianos at a lot of different places the main factor obviously was how in tune they were, but then came the brands. Bosendorfer is my own personal top of the list. But yet these sound entirely different to Steinway or Bechstein. Yamaha acoustics I always personally found characterless (although I like Yamaha electronics). Then there were some nice surprises like Broadwood Green Frame (lovely), or Bentley (awful). My fingers have now become accustomed to the weights again - after years of just playing electronic organs and keyboards. Out of all the "keyboard" pianos I've played though I really rate the Casio WK Grand Piano on ZPI Sound Source.
