Steinberg "the grand" is my favorite virtual piano. I tested against several "big ones":
Acoustic Samples Kawai EX
Garritan Steinway
Bardstown Bosendorfer
Sonart Audio Bosendorfer 290
EWQL Boesendorfer 290
EWQL Steinway (Colossus)
EWQL Fazioly (Colossus)
Sampletekk Steinway Black
Sonart Yamaha C7
Adam Serafin's Piano
And Steinberg "the grand" always win. At least to my taste.
Better even: this Kawai piano is from wizoo and also were avaliable in Halion and EXS format. I use it in NI Kompakt because is much more lightweight than with the Steinberg interface.
