Let me add some context: I didn't spend much time with the bread and butter sounds (piano, EP, organ, clav, gtr, etc.) but what little I played didn't impress me much. Serviceable, but a bit déja vu.
I was mostly interested in the synth stuff; you know, Roland's pads, synthleads, bell-like sounds etc. They have traditionally excelled at that, and my first impression is that the new Fantom has it in spades, and it seems there's plenty of new flavors to discover and savor.
