Going for the original motif or the Fantom S? Why not Motif ES or Fantom X?

I'd definitely vote for roland then. The Fantom S can be expanded with 4 SRX cards, which i explained in the other thread. the Motif Classic is not nearly as expandable, and the stock sounds won't fit your orchestral style as well. But, if you don't plan to expand the Roland Fantom S, I'd maybe recommend motif for the better piano sound, maybe a toss on string sounds. Motif flute is much better than Fantom flute. Motif better percussion. Everything else a toss. Fantom S with SRX expansions will by far outshine Motif though.
