All of it sounded like a Classical Piano but the Kawai and Ketron sounded the best; followed by the Rolands and the Casio. Since its played by a talented pianist, picking the best piano sound is difficult since they put the instrument to the best of what it can offer.

Even the classical piano in the GM bank of East West Quantum Leap Goliath software sounds dynamic and warm to me; but I got years of practice to do to reach even half the level and grace of this wonderful pianist

Thanks AJ for these comparison videos.
