Thank you! For the piano, ppl would in general more recommend sampled libraries like Keyscape or Garritan CFX for the ease of use and immediate realistic sound. Pianoteq appeals mainly(&especially) for pianists as it does react very musically like playing a real acoustic piano(although the touch of keyboard is not the same). But production wise, if you want to make Pianoteq sound more realistic, there's a need of some extra fiddling.
