Well, I've borrowed a friend's server with I2S out, and compared with analogue. Both are superior to the USB connection, such as providing more harmonic depth, more "air", less grain, tighter imaging - overall a bit more musical.
Plus, avoiding the additional processing required to convert the USB signal back to I2S format just makes sense to me and others.
